So I met my current bf about 2 years ago and I've been in love with him since. I stayed by his side even when I wasn't ready to commit. He was what I wanted so I didn't give up. We've been living together for about  7 months now and I've been feeling like I can easily stray. I'm not as interested in spending time with him much less having sex with him. We've been through a lot and he finally decided to commit fully about 8 months ago and ever since then it's just not the same. Idk if it's because I don't have to chase after him anymore or if I'm just burnt out. I find myself wanting other people. Idk what's going on. We plan on moving to another state soon and I'm hoping this changes everything. When we went on vacation a couple months back, everything was good. We had sex every night and I loved spending every min with him. That's why I'm not sure if my job or everyday life is what gets me feeling this way or if our relationship is to its end. Anyways, he's even brought up marrying me once we move. I'm just not sure what our future holds yet. I've tried telling him things aren't the same and he genuinely tries to talk to me and help me work through why I'm feeling this way, but I cannot figure out why. Someone give me some advice or things to try?
