Lost and confused🙁

I have been with my man for 3.5 years and life was great...up until 4 months ago. He became distant and didn’t want much to do with me. Every time I voiced my concerns, he would dismiss it. Slowly, I lost feelings for this man I once couldn’t keep my hands off of🙁and now he’s slowly coming around to wanting to be around me more but I just don’t have the same feelings I did because of this distance he placed on us. I don’t know what to do and I feel like every time we talk, it’s cold and fake. I want things to work out but I feel like he’s ruined things between us. Is there any advice you guys have on this?🙁
