πŸ™ŠπŸ™‰πŸ™ˆ I need advice .....

So I'm back with my ex giving it another chance.(broke up before bc I believed lies his baby momma was telling me bc she didn't want him to move on like she did) Anywho when I was still single I started talking to this guy and we became really good friends. When me an my bf got back together I told him about my friend. He doesn't mind it he just keeps saying that my friend probably just wants to use me. When in all reality more an more it's starting to feel as if my bf uses me as a sex toy an when he's not horny I'm of no use to him. Sorry for getting side tracked. But more and more feel like I'm falling for my friend he talks to me more than my bf does and asks me how I'm feeling an actually has a conversation with me. When I'm depressed or can't sleep he calls me and talks to me until I'm better. I was with my bf the one day when I felt really depressed and he looked at me and told me to stop being such a baby. I thought I loved my bf but now sometimes I can't stand to be in the same room with him bc of the way he acts most of the time and. He used to be so sweet and caring but now it feels like I barely know him anymore. I don't know if it's a good or bad thing but more an more I feel as if I'm falling for my friend.
