Lonely? (Vent)

So my last friend doesn’t really talk to me anymore. She’s with this guy who is like really controlling and is always taking all her time. He doesn’t really like let her go out. And if she does he gets mad and all kinds of hell breaks loose. So basically he makes her whole world revolve around him even though they have a kid together. He still makes everything about him.... but anyway we were pretty close friends and he just kind of booted me out of her life so I stopped trying because I mean am I wrong when I say it’s not that great to have to make all the effort to be someone’s friend when they act like they are to busy for you? And before that my best friend of 9 years well found out she was talking shit behind my back and only ever hung around me because I would take her places with me and buy her shit... and well I could go on about other “friends” that I have had but it’s a really long story. So basically I have had shitty luck with friends and well right now my boyfriend is my best friend. Which I don’t get me wrong I LOVE that he is my best friend and I can tell him anything and everything. I love where our relationship is at. But I’m also lonely because I have no one else to talk to... I have no other friends and it sucks... But I guess that’s life right? Sometimes it gets lonely.
