Bf makes me wish I was with my ex..

I feel so shitty but my ex always had time for me and we broke up because we both had too much going on in our personal lives that it started to impact our relationship. And it was largely just me needing to figure my own things out.

But a lot of time went by and I sorted my life out and I met someone new (my current boyfriend) and things were amazing in the beginning but now I feel like he got comfortable. And we don’t talk as much and I honestly hate the lack of sex we have and he’s always tired. And idk. Feels like the spark is gone. I wanna talk to my ex but I don’t want to hurt my current boyfriends feelings

I feel like shitbag of a person because both were good guys and I think that I don’t deserve them. But it’s hard because I know my current boyfriend loves me I just feel really unloved.
