Your a selfish one aren't you? I mean here you are going out and cheating on him, then your planning on ending the relationship too - all without telling him or talking to him. I have no idea what else you do in your relationship, but these are two terrible signs of a bad marriage in the making. Honestly you two need a sit down, no tv/radio/computer/ipods/phones off kind of one on one talk. 1. You need to come clean on your cheating. 2. You need to discuss what this means to both of you. 3. You need to discuss how this will affect both of you in future before and during your marriage. 4. You both need to decide TOGETHER if marriage is the right road or if now is the time you two part company. On a more personal note, you need to seriously work on yourself. You need to figure out why it is you cheated, why it is you felt you needed to - and also figure out how it is that you can not talk to your partner in a relationship. If there is any other relationship issues YOU have you need to work on them. It would not hurt to seek out professional therapy sessions - everybody, even those who do not need it should take it up. Learning about one's self is not a bad thing.

You know the answer, he deserves much better than you.

Do him a HUGE favor and let him go !! He deserves someone who will truly love and respect him.

6 months, you must be so proud, why not show him this question and see what he thinks ? :-)

You did not cheat him for 6 months! sounds great!! The good thing is that you have only realised that you have cheated him. But you have never regreted for the cheating you have done to him. This shows you have no love for him! In future if you are sure that you are not going to cheat on him and love him in all sincerity and honesty than you can continue.....incase you dont trust yourself, you will just need to tell him the truth and leave him!
