(F/19) I think I'm falling out of love with him (m/18)

I've been with him for almost a year, but I don't feel the way I did before. We've had a lot of issues, and we had to take a break at one point. I cate deeply for him, but I don't think I'm in love anymore. I can't decide if it's my depression and anxiety getting in the way, or I really don't live him anymore. I feel so terrible about it. So guilty. Weve been looking at new apartments so we can move in together, but I'm scared to. What do I do? ? ?
