I couldnt say without knowing how they treat the child. My relationship with my partner does not necessarily dictate how he is with his child.

Does it affect the children? Certainly. Does it negate the person's parenting skills? No. It's about the parenting skills, not the ability to stay loyal to their spouse.

No. . Raising children is *not* a one person job. Sometimes it's not even a 4 person job. . I was/am a single father. One of the ways that is different from a single mother is I think in terms of goals and methods. I measure my performance. I calculate the answer, regardless of my feelings. . I know that simply trying hard or doing one's best does NOT constitute success. People try real hard, do their best, screw up and fail all the time. Being good at something means producing good results. . Oh, anything I say about 'people' means me too. . I've seen people who weren't good at their jobs because they weren't skilled. I've seen people who weren't good at their jobs because they couldn't work with others. There are many many craftsmen who are lousy house builders because they hurt the performance of everyone around them. Being skilled is worthless if the results are shoddy. . Parenting is, at least, a two person job. My standard for what constitutes 'good' parenting is the performance of the standard traditional nuclear family. That means one of those parents is on site and on the job at all times. Subcontractors are OK, within their limits, but they aren't and don't feel responsible for good quality results. . There is no such thing as a 'good' single parent, in my opinion. There is only lowering the standard to whatever level makes you 'feel' good about yourself, without regard to the needs of your children. There is only conning your children, and yourself, into believing that your doing a good job. . Raising my children is the most important job I have. Nothing else even comes close. I would give my life for these children, either all at once or one day at a time. . So, in my not so humble opinion, if "Your spouse - your best friend, help, and comfort - has betrayed and is cheating on you. Your marriage is cold and a lie. The secure foundation of your family is broken and unsafe. Is your spouse truly a good parent?" . Hell no! They have *severely* impeded your ability to do your job. They have made good results impossible. Were this a regular job, and the client - your children - had the wit, you would both be *fired* as incompetent. You are unable to work together, and at least one of you - the cheating spouse - has chosen to screw up this job to pursue their own interests. . To me, being a good parent includes taking care of my partner. I will love her. I will support her. I will comfort her. I will be kind. I will be patient. I'm not going to let her get hurt. I'm sure as hell not going to hurt her, myself. I'm not going to get this done even half right without her. . And the same goes for her. . When you're parents together, it's not about you, either of you, any more. If I cheat you, or you cheat me, the children got cheated. .

Let me ring in on this. Married 37 years, husband cheated at year 12, we had four daughters aged 5, 8,9 and 10 and he messed all their opinions of relationships up with his behavior. Was he a good parent? No, a selfish person. This past May, he revealed he has continued cheating for the past 26 years, the most recent 13 with my friend. There have been 6 ppl. THree of them my so called friends. He is not a good parent, was not a good parent. HE was always thinking of himself first, short with the children, a liar, never took care of our home as to maintenance, turned all my intuitions back on me so that I felt guilty for asking. Master manipilator. Me? I have lost both breasts to cancer, been diagnosed with MS, spent 10 days in the hosp. with ischemic colitis out of the blue, etc. THis is in the past five years. Now he feels all clean, he cleared his conscience. I am destroyed and angry. No one wins. Anyone who cheats cannot possibly be thinking of their family and if not, they are not thinking of how their actions will affect their children. My grown daughters are suffering from this today. All of our worlds are torn asunder. Even his. I want to kill my friend. My rage has no bounds. I have basically been terrorized emotionally. I did ask, I did go for counselling all those years, he went with. He lied, denied, cried because I asked, made me feel guilty. HE is a horrible man.

if your spouse betrayed you it doesn't mean they are a bad parent, it means they are a bad spouse. Being married and having kids are 2 different situations. Granted it is not good for a child to go through this, but some spouses are selfish.

Just because you spouse is not necessarily the partner you need does not mean that he/she is not a good parent. Being a parent is different from being a partner. YES you may question the loyalty he/she may have to your family has a whole but this person can still be a loving, caring, responsible parent. You should try to separate your marital issues from parenting - it is not fair to you, your spouse or your children to lump the relationships into one. Best of luck to you!
