Is AUTHOR wrong in the post ? POST : Since my best friend kinda brought us together, she knew everything happening between me and my boyfriend. When I introduced them, they got along really well what I appreciate since you want your boyfriend to like your best friend and the other way around. 

So, my boyfriend has an entirely different friend group than me and my best friend and he takes me to a lot of parties of his friends. He also invited my best friend to come and I even motivated her to come and stay at my house with my bf and me for that night. 

That evening was a Desaster for me. My bf loves me and couldn’t stop telling me how much he loves and appreciates me that night, but at the same time, it bothered me so much that he repeatedly told me how GREAT my best friend is. “Yeah she’s great, she should stay all of the next day, come sit on my lap, come hold my hand, you can sleep with us in a bed” etc. He’s a pretty touchy person (especially high) and I don’t have a problem with that, but holding hands with my best friend he does barely know Is just so wrong and I told him that, what he understood and promised he won’t do again. She, on the other hand, did nothing about, how it seemed. 

I regret that I tried, or more I felt obligated to integrate my best friend into my bf’s life, because, yes, I may be a bit jealous and also feel threatened by how she straight up manipulates people to see only the best in her, because me as her best friend knows that she also has dark sides. 

I tried to talk with her about that i don’t like her so excessively trying squeeze into this hole group and between, or more like into our relationship, but every time I try to talk with her about something that bothers me personally about her or just about the way I FEEL about something (which I can’t help), she just takes my arguments, turns them 180 degrees and suddenly it’s all my fault and she manipulates ME into feeling guilty about not trusting her, being mean to her, not appreciating her love for me etc. Since that, I want to confront her but at the same time feel guilty confronting her, especially because she brings up her mental illness (depression) as the reason for so much stuff she does, which I don’t see as an excuse not being able to listen a friend who wants to share a problem. 

Since me and my bf haven’t dated long yet and it’s my first real relationship where I actually feel loved and also love back, I may feel threatened by my best friend just hopping into the situation. But are my arguments valid here? Or am I over reacting because it’s just a new situation for me. And I know it may seem like my bf isn’t trustworthy or something, but believe me, he can’t stop talking about me to his friends and family, they always tell me and it’s really cute. I just want to solve this, because it’s not me vs my best friend, but us against the problem, and I still love her as well. I’ve already tried to talk about it with my bf, but he kinda doesn’t understand my point.

Best friends is getting close with my boyfriend and is jealous for him being now my priority, so I started confronting her but she turns it seeming like it’s all my fault and making me feel guilty.
