So, a little back story, my SO and I lost our son at 19 weeks gestation just a little over 4 weeks ago, he died during birth, very tragic, very stressful, very sad. We started off fighting over our different ways of grieving but changed to smaller issues that we used to have at the beginning of our relationship (trust, clingy-ness, space, opposite sex friends, the normal). We have talked it out and figured we were arguing over the smaller things because it was easier to deal with those issues than for us to deal with our loss.
Well, my anger and smart mouth got the best of me and I broke up with him during a very heated argument and he got onto a dating sight (MyYearbook) and started talking to a random girl that night. He said he started talking to her because his friends were not answering and he needed someone to talk to. We are back together but he still talks to her and thinks she has put him in the 'friend-zone'. They have never met in person and he wants to hook her up with one of our guy friends. She was all for it and so was the guy friend but I ruined that plan (my SO wanted to invite her and him over while I was not home....strangers in my house does not make me a happy camper. Just a territorial thing not because I don't trust him). We have been dating for about a year and a half and together exclusively for the past 8 months. He and I live together in my house with my 4yo daughter from my previous marriage. He doesn't have a car so he uses mine to get to work and since he doesn't have a bank account mine is the one used for direct deposit....Anyhow, him and this girl still talk/text and he has explained to her that he isn't interested in her like that, never was, and only wants to be with me. She told him that she understands and that it didn't matter if he was interested because she doesn't have time for a boyfriend, that she works too much and goes to school full time and is still hung up on her past 4 boyfriends.
My question is: Should I feel threatened by this girl? He has only known her for 2 weeks. Despite how they met I understand that in his eyes they are just friends, and I have even agreed to met her in a group setting. But I have used that line of "too busy for a boyfriend" to be able to get closer to a guy I was interested in without looking too pushy. Do you think she might have other intentions?
Thanks in advance for your input :)
