<human>: My boyfriend, Tod and I have been together for 13 months and we are doing well. I'm truly grateful to be in a relationship with Tod who I love dearly.

So...I have some issues with jealously. Last August, a girl who Tod had a fling with (that happened a few months before we started dating and it lasted only one night when they were drunk) visited our city to see her friends and she was staying at Tod's apartment for a few days. That wasn't Tod's idea. His roommate approved her staying at their place, after all they were friends. I wasn't very happy at all and got upset when he told me. So he managed to avoid to see her till that day when he thought she left the town. He only discovered that she was still there when he arrived to his apartment. He told me by text and I overreacted. But I decided to let that go and we moved on.

So today...Tod just told me that the girl texted him if he wanted to hang out this weekend. He said yes. I was pretty upset because I felt like he chose the girl over my feelings, even he knew that I'm not comfortable with that. He told me that other people will be there. Also he suggested her to hang out at his apartment and I wasn't happy about that either. I have work this weekend so I can't be there. If I don't have any plans, I won't be there anyway cuz I don't feel comfortable to be around her. I asked him if he wanted to hang out with her. He said yes and it made me upset even more. He decided to cancel his plans with her for this relationship but I protested and told him that he can hang out with her but I won't be there. He said that if he wanted to do something with her behind my back then he wouldn't told me that in the first place. Also he told me to let that past go. But the point is that I felt like he chose to be with her over my feelings. Am I overreacted?

Can you condense the text into three sentences or less?
