Help me find out why i’m unhappy?

Hey guys,
so i’m not 100% sure why I've been unhappy lately. I don't know if my relationship with my boyfriend is making me unhappy or if the reason i dont don’t do anything with my life is making me unhappy. Let me explain. My boyfriend and i used to do a lot of fun things together, we used to go out on dates or on little adventures. now we don’t do anything anymore, we barely talk much or we barely hangout anymore. i’ve asked him why and he said it’s because all I've done for the past two years is complain about the past and what he has done is horrible. let me say that in the past he used to follow a lot of bikini girls and like their pictures. i asked him why he did that and he said its because at the time he didn’t know what he wanted and a few years ago he finally realized what he wanted in life and he knew he wanted to be with me. however, i still bring it up and i still feel hurt by it and it bothers me as well how we don’t go out on dates. Now I don't know if im unhappy with my everyday life as well. All i do is go to work and go back home or hangout with my boyfriend at his house. i used to have a good group of friends but we all stopped being friends so i dont talk to anyone or hangout with anyone besides my mom, sister, dad or boyfriend (if he wants to hangout) i used to go to the gym everyday, i used to hangout with my friends everyday and now i dont do any of that. so I don't know if im unhappy because of my relationship or if im bored with my life.
