<human>: Fiance and I have been together 4 years. I love him, but have lost almost all attraction to him. We fight quite a bit. He always does the same thing: when we fight, he changes for a little bit and acts better, gets my hopes up, then goes right back to ignoring me/my feelings. I kind of feel like I can do better, but I'm scared because me and him get along so well when things are good. I'm guessing it has a lot to do with us being young/the fact that I've never really been single and am kind of curious about that as well. Sorry if this doesn't make a lot of sense.

Can you condense the text into three sentences or less?
<bot>: lost attraction to fiance. How do you decide if you want to end a long term relationship when you are comfortable but not happy?
