Brothers,

I've been dating this girl for over a year now. Overall, she's a great gal - she's caring, honest, thoughtful, positive and in general seems to be a good person. We're both in our mid 30s.

However, she's also a very friendly person, to everyone and that also includes other men. We recently had a situation at a wedding party, where we both got introduced by a groom to another couple. A few minutes into the conversation, she left without saying anything or at least I didn't register it. A few minutes later, I see her at the bar, talking with another guy - I recognized him from another party so didn't think too much about it. I was glimpsing at them from time to time - noticed the guy touch her waist briefly as well but she didn't react. Soon, two more guys approached her and she was chatting with all of them. I didn't get involved and when I was done talking with the couple we got introduced to, I grabbed some food and went to a table outside to eat. She came back to me shortly and I confronted her - she said she went to grab us some snacks and on the way met a guy she knew and went to talk with him, she said they all were taken and with their partners at the party. She admitted she's bad at drawing boundaries with people in general (she says she's a people pleaser) and said she will work on that. That was a month ago.

Now she's going with her 3 girlfriends and a guy from work on his boat for a few hours of sailing. Apparently it's something they won last year in a charity event they do at their work - the sailing was offered by the guy on an internal auction and everyone was bidding for it. Again, apparently the guy has a wife and wouldn't be interested in any of them. She's also invited me to their next work BBQ party (which is before the boat trip) and said she will introduce me to the guy. I'm not very enthusiastic about it - I'd feel like a cuckold.

I don't like any of those situations. Especially the first one, I felt really bad after it. Perhaps if it didn't happen I wouldn't be too concerned about the boat trip.

What do you guys think? Am I overreacting? How should I proceed?
