<human>: Condense the text into a few key points

Okay so I'm the type of guy that has a lot of friends that are girls and I still talk to my exes and girls that I've had flings with in the past. I do this because I genuinely am just friends with these people. 

One time in particular with a very close girl friend of mine (Taylor of whom is like a little sister to me) I was with my SO and Taylor was coming off a break up so I wanted to spend time and be there for her as she was there for me. I asked my SO if she wanted to come and she said no it's fine and then later proceeded to cry because she didn't feel special - in the sense that I was setting up a surprise thing for my girl FRIEND. I ended up going anyway.

Two weeks ago I went to an amusement park with Taylor and some other friends and didn't invite my SO and she got hurt again. 

So she ended it and brought up the surprise thing and now is being confusing in the sense that she says she just wants time for herself but is always texting me about how thinking about it pisses her off. I just want her to trust that I don't have feelings for these people and only her. I've never hid anything from her. She says that she's done but still shows she cares by arguing and insisting on still being "friends". She claims she's not trying to argue with me to fight for her and for me to fix things but wants to be friends. Just tonight she asked me who I was with when I posted a snapchat picture. In my mind it's like she's following my every move still and clearly still likes me but needs help getting over the Tayor situation. I've already apoligized, stopped talking to my ex for 3 months, and done everything I could think of. Is there anything else I can do?
<bot>: Girlfriend can't get over the fact that I have close friends that are girls. She broke it off because she can't get over that. How do I get her to trust me?
