<human>: I've been with my boyfriend for 1 year and a half now. We, as people, are completely but i mean COMPLETELY different in everything whether it be our personality, what we want from the relationship (for example he wants me to be giving him attention all the time and hold his hand and hug him and kiss him all the time because that is how he is with me but i am a completely unemotional girl who has trouble being "sticky"), or even the way we act. 

Saying all this, the relationship has had it's ups and many, many downs and this all makes me wonder if in the end it is all worth it? I mean do you guys think I should just learn to accept it the way it is and deal with it? 

We have talked about compromise many times but in the end, we cannot change each other. The things he does that bother me go away for a few weeks and then he slowly goes back to his old self. I am the same way. I'll be more cuddly but eventually I go back to my usual independence.

 He has never in any way, ever been disrespectful or hurt me or anything, just to clear that up and neither have I. I think it's because our personality clashes which cause massive fights. He is a great boyfriend and I love him but I also wonder if we will ever get over these huge differences? I wonder if it's worth all the exhaustion in the end. 

I'm just lost as to if this is all worth it in the end. I know he isn't the only fish in the sea but I worry I might regret my decision of breaking up, and at that point, it would be too late to fix things. I have a hard time seeing myself without this person in my life..

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My bf and I are completely different people and I worry that by giving up, I'll regret it in the end.
