I'll try to keep it brief. Divorced last year after a miserable decade of marriage (he left me for someone else). A short while ago I met a guy through mutual friends, who divorced also around the same time. We really hit it off and for the past month have been seeing each other every week, with almost daily contact by text. We agreed early on that it was a non-serious thing, which seems to suit us both. I really like him and it appears to be mutual.
It's been going well, I thought. But something happened on Friday night that has had me a bit worried and upset. We had a night out with our mutual friend group, who don't know about anything going on between us. Beforehand we agreed to 'behave', and I made an effort to circulate among the rest of the group. There was a lot of alcohol going on.
Late in the evening I noticed FWB hadn't spoken to me once. He was spending a lot of time with some of the other girls in the group, one in particular who he had his arm around a lot and she was being equally flirty. We changed venue and when I was at the bar he appeared and was flirting with me. After that someone else in the group said to me that he was being very flirty with the other girl and had now moved on to me.
Not helped by alcohol I was getting a bit neurotic in my head and eventually pulled him to one side. He was very drunk so couldn't really get much sense out of him and I think I made an utter tit of myself by telling him I didn't really want to be anybody's 'second choice' and that I was going home. He persuaded me to stay - in the meantime the other girl had rung him (he missed the call) and it appears she had gone home. Everyone clearly noticed that something was going on between him and me and I'll admit I was a bit embarrassed.
I took him home then and spent the night there, leaving him with a raging hangover Saturday morning. I'm completely confused by his behaviour, my reaction and what the hell I do now. I have a tendency to get very insecure and anxious anyway. And now I'm wondering if I can do a FWB situation. Please be gentle but - help?
