Girlfriend of 6 months was in a relationship with me and other man
TL;DR: Girlfriend was in a relationship with me and another man for 6 months. Was with a woman for roughly 6 months. I had happened to accidentally leave my phone sitting unlocked somewhere while I was busy doing something else at work and this girl put her information in it without me knowing. I thought she was attractive so I decided to add her back and we conversed for a couple months. I had gotten to know her very well and she showed extreme interest in me. So I decided to ask her to my girlfriend. We had a good relationship she was a bit inconsistent with communication and things but we had wonderful conversations of our future, and she always told me how much she loved me and made sure I always knew I was cared for and appreciated and we always had a great time when we spent time together and the chemistry was there. She talked about wanting to have kids one day and having a house together amongst other things. And then one day by a friend who knows the other guys cousin it came out that she had been in full blown relationships with me and this other guy the entire time and she scrambled to get me on the phone to tell me she cheated.
She expressed that she wanted me more than him but didn’t want to hurt him, and said all sorts of things on the phone that night. basically she wanted to have us both and I was completely unwilling to go along with that but by the looks of it if I would’ve continued to play my role and be a part of this she would’ve continued with it. I told her I would tell her other boyfriend what she did and she really didn’t want me to. So I ended up telling him and I received messages from him of her calling me names for that and other nonsense the next day because she went right back to him to try and resolve things the day after. I then had a final conversation with her today and she tells me that she loves him and is gonna choose him every time. In my mind I believe that she really wanted me but she understands and know that this other guy is gullible / naive and will forgive her for her mistake which she already said he did, meanwhile I’ve made it very clear that the relationship is done and if she says anything further to me I will tell her boyfriend what she says so now she’s trying to flip the script like she doesn’t want me because she already knows I wouldn’t put up with this or forgive her and I will tell her boyfriend if she continues to show interest in me or keep things going with me. What do you guys think do you think I’m right or was everything a lie and how do I get over this. It hurts because I mind my business I don’t bother everybody and this woman came into my life and disturbed my peace for seemingly no reason it’s hard to trust anything anybody says anymore but I’m grateful for the lesson I was able to learn.
