Search Results: text him happy birthday

I've been with my boyfriend for over 11 months and it's coming to the point where I can't take his behavior anymore.
Whenever we are with each other, it's decent. I feel happy. But we don't see each other often. Then there are times when we don't see each other where he doesn't give me much attention. He knows I need attention but sometimes he doesn't reciprocate with me. I feel like I do most of the work with the texting, genuinely wanting to talk, etc. I get it we both have lives outside of the relationship but I feel like it doesn't mean you have to completely shut out your partner on days you are busy. You should at least say something. But with him I always get the vibe of "oh the gym first", "oh work first", "oh friends first"... when it comes to being in a relationship, yes you make all of those things a priority but you also should give your girlfriend a chance to be high in the list as well and balance everything out.
And I feel like I do more for him than he does for me. For example, I'm naturally a loving and caring person. I love saying goodnight I love you but then last night he didn't respond to it.
Guessing he was busy... but still it hurts. And I want to do so much for his birthday and I'm trying so hard but for my birthday he just said happy birthday and didn't give me anything making me feel quite shitty...
So what should I do? I've discussed my issues with him beforehand but it seems like nothing seems to be fixed and he can't change. He tells me he loves me all the time though.
