<human>: Can you succinctly summarize the text in 1-3 sentences?

I met this girl late February and we hit it off like I haven't ever experienced in my life. The chemistry was amazing, the passion was definitely there and everything was looking up. Unfortunately, one of the very first things she did was to text her ex to tell him she found someone else. She said it was consideration to which I said it was to insight jealousy. Low and behold, jealousy was what came about. He came storming back into her life with a newly found passion, (this is after six months of him essentially emotionally abusing the poor girl) a passion embraced with open arms by her. 

After dealing with that for a few weeks, I had enough because I knew it was wrong. I told her for us to truly be together, she must go back and see that the relationship she had been clinging to in her head didn't exist anymore and for her to open her eyes to how bad of a person her ex really is. After three weeks, she came back to me. Unfortunately he was still lingering and she wouldn't let go. I told her that's a must for our relationship to be successful and after a couple of months she finally made that commitment and told him off. Although she told him off, she neglected to mention me due to consideration of him once again. 

After her finally giving him the boot, I was met with a love I had not experienced from her, yet I found it increasingly difficult to trust her after everything she put me through with her ex. She has predominantly male friends and is upset when I question anything to do with them and was extremely upset when I told her that her keeping her ex as a friend would only cause more conflict in our relationship.

Frankly, I don't know what to think about the situation anymore and would just like some support or insight as to where I should go from here. Anyone with similar experiences? Did you make it work? 

Thank you.
<bot>: On and off again girlfriend couldn't get over her ex leading to serious conflict within our relationship. She finally got over him, yet something seems off. Can anyone give advice?
