I have become that friend

So my home girl Tonya recently meet this young man by the name of Ricky. One night after the club I lock myself out of the house and have to spend the night at her House I get to meet him. I don't like him after 5 mins of convo. Maybe its because he's loud or maybe its because he says bitches whenever he talks about any female period. He even referred to us as bitches during this talk. And he's a one upper. Either way I didn't like him. She asks how I feel about him later now and I tell her the truth. She gets upset and says that I don't like anyone that she ever talks to.(So not true I loved like 2 of the most recent ones)

Now fast forward like a week. tonya and I are in the club and he comes in with his crew. I speak because I have some home training but basically keep it moving. So later on that night in the club I meet his brother. Now his brother says all the right things and I was trying to see what was up for chilling later. This was after a bunch of drinks in all parties in involved. Nothing happens.

So the next day we have shopping trip planned with the fave 5 and he comes along too. At tonya's he says that I was talking shit about him to tonya in the club. I tell him "Not so much he never was even was on my radar." So during the hour car ride he decides to tell the whole truck "so you and my brother are going to fuck huh". I can honestly say that was most embarrassing things to happen to me in my adult life. This ass kept bringing it up for the rest of the day so I was done with him after that and just basically avoided him the rest of the day.

So monday tonya came to the house after being with him all the rest of the weekend. And wanted to talk about him again after talking to me on the phone 5 mins before hand about him. Oh did I mention that she now changes her set plans with me to be with him and doesn't tell me until the last minute. And when she calls its always about him. And she calls me when she's with him and puts him on the phone. That's too much for me. And they are one of those super affectionate couples (kissing and licking at one point).

Well seeing that she was no help I called my C-money and bitched to her about them. Well she boiled it down to two things. (1) its new for her its only been 3 weeks and (2) I'm being a hateful bitch. She wonderfully pointed out that after a long (sahara desert) time of being single I have become slightly bitter(lemon lime). So me not liking him from the beginning has completely harden me against him (true) and I should try to be nice.

Part of me was like fuck it and just keep it the way it is only being around him when absolutely fucking necessary or just grin and bear it. I really like part 1 because I'm moving and don't to see his ass anymore any way. What should I do?
