It's only YOUR opinion that he'll be 100% dedicated to football. If you love him and want to be with him, then you should work things out together and tell each other your worries.

First of all, what has your boyfriend's love of "footy" got to do with anything here? Second, since this is the Teenage relationships section, I am going to assume that you two are both teens (or that you are at least). That being the case, you two are still rather young to be thinking about marriage. You both have much maturing to do yet. The fact of the matter is that teenage relationships rarely last and that is OK. It is during this time in your life that you are supposed to be figuring out what you want out of life, what you want to do for a living, and what do you have to do to get what you want. It may be that you will marry your current boyfriend eventually, but that is not likely. What you need to do with any boyfriend is look at the whole package and decide if he is what you want in a mate. Does he have the good things for which you are looking? Can you live with the things in his character that you don't like? No one is going to be perfect and you should not try to change the person whom you marry. You should find someone whom you can take as is. If you don't think that you can accept your boyfriend's obsession with football, then it may be time to start looking for another potential mate. You are both still young. You still have time to figure all of this out. Just don't go rushing into a long term commitment until you are sure that it is right.

If you truely love him with all your heart, then you will back his dream, and stick behind him 100%. Maybe he would dedicate himself more to you, if he saw that you respected him, and stood by him no matter what. If you had a dream, you'd want him to do the same. Ask him, if he would do the same, if he would back you up and stick by you and support you if you had a dream you wanted to fulfill. Ask him what he'd do. I think you should just be there for him.

how do you know hes not dedicated to only football? people that are %100 dedicated to something usually dont have time for a relationship. you have been in this relationship for a year and a half? (read comment above) that sounds like hes in it to me. do you want someone that is doting on you all the time, or someone that has other interests, and lives and breaths for you? figure out what YOU want. it sounds to me like he is in this relationship, and you are the one with doubts. think if this is what you really want.
