I'm posting this in here because I don't know where else to post this and get serious responses rather than stupid ones. A little background I've been hanging out with this girl off and on for a few days and it's a female that both my roommate and I know. When she comes over and we're hanging out in the living room he kind of lingers around and talks with us every once in a while. Well Friday night she came over and my roommate left the house and while he was gone he was texting her. She told me he was texting her and and somewhat described what he was saying short of actually showing me the texts. Basically he was telling her that they needed to hang out and get to know each other. Saturday came around and I went to a wedding with this girl and she ended up wanting to come over and hang out and explained that my roommate had been texting her off and on all day. We kind of joked back and forth about it because of some of the texts and what they said. Then today she texted me and asked me how my day was and then I proceeded to ask her to come over tonight and she said that my roommate was going to take her to a movie. I just kind of replied with "ok". Now I can't even explain to her why I'm upset about this.
