Search Results: liking a friend''s ex

First of all, the two of them started off as dating. They were messing around with each other for 2 months. In the end, they realized they don't work out as a couple so decided to remain as friends. They became best friends of 10 years. It is so long ago, so I was fine with her and the whole situation. I never thought she would still have feelings for him. My fiancé is not attracted to her 10 years ago & obviously has never touched her since. He has been through other serious relationships. We have been together for 2 years and we are stable. I know he loves me and it is not about trust. She needs to get the message that she is not respecting me or our relationship for 2 years, so sorry, you are out.
Since the first day, she avoided to meet me. I find already find that weird. She lives 5 minutes away and makes up a lot of excuses for months. The funny this is, she will be free when it is only my boyfriend. When she asks him out and she knows I'm coming, she just disappears! That happened couple times. Maybe I am thinking too much, but come on, it is shady. When we met, she won't follow me on social media and made me follow her. Isn't that rude? She doesn't like me for sure and I don't care if it's because of me. However, if it is because of my boyfriend, then that's different. I think she has unrequited love for him and she is hiding it! She tells my boyfriend that I am showing red flags that I will cheat on him whenever we argue. She doesn't even know me. She is a problem now and will be in the future. I was willing to make her part of our lives but within the 2 years, she just wants to be part of my boyfriend's life. She is alienating me and not liking me for no particular reason. She has not once try to be warm to me is pretty fishy. And expect me to be okay with you asking my boyfriend out alone? My boyfriend agrees that she is being shady after I pointed out the points. He has no problem cutting her out. I just feel bad because it's not in my nature!
