How to be more competitive and less of a push over in a relationship??

I think it's something which is built into your nature, and therefore not so easy to change. My best friend told me the same thing, and after that I made an effort to try to stick up for myself a little more. But it'd been the same situation with her always getting her way for so long, that when I tried to change it she said she preferred it how it was before. So even though she thought she wanted me to be more outspoken, it turned out that she preferred things how they were anyway, and it was more of an observation that I didn't stick up for myself.

If he definitely does want you to become more outspoken, you could gradually speak up for yourself a little more, by starting with small things which bother you. Maybe your boyfriend always chooses where you go out for example, and one day you could say to him that you'd like to go to x place that day. As you gain confidence, it might start to become easier to talk about your feelings, as I find it's harder to speak up when someone's behaviour annoys you; as opposed to just saying you'd prefer to go out somewhere else. If your boyfriend does something which upsets you, then tell him. It will be difficult at first, but as long as both of you are willing for things to change; then it should become easier with time as you gain confidence.

Good luck- I hope it gets better.

when he goes to kiss you headbutt him, id like to see him predict that
