I wrote earlier on this and can’t seem to make a decision. Any input would be greatly appreciated.

I met someone through an on-line dating site. We hit it off great and have great chemistry. After the 4th date I found out he had gone out with my twin sister about 6 months earlier. They had only gone on 2 dates and quit dating because she didn’t want or have the time to invest. My kids are the ones that found out he had dated my sister because they talk to their cousins a lot and when they mentioned the details and his name, they all discovered it was the same man.

Understand that I am a very honest person and feel communication is what makes or breaks a relationship, So I brought the information up to him and he acted sincere in his answer. He claimed that he didn’t realize we were related. He had not thought about her since it was several months ago and such a short encounter. I believed him, but it really upset my 16 year old daughter. She thought he was sketchy. She had only met him once and seen him twice, so for her to form an opinion based on the fact that he had gone out with my sister I felt was unfair. But it made me question things more.

The whole situation makes me a little uncomfortable, but I’m also drawn to the guy. My sister and I do not have a good relationship and haven’t for several years. I won’t get into that, but we don’t speak except to say hi at family functions. So I’m not sure if I feel uncomfortable about him dating my sister or the fact that if we continue to date that he’ll run into her and we all may feel awkward.

The other thing that makes me uncomfortable is that my sister and I look a lot alike (we are twins). New Friends can’t tell us apart at first. So I questioned whether he was being honest and whether he knew or not that we were related. I gave him a few days to gather his thoughts and hoped he’d open up and tell me honestly. I explained my feelings on the matter and he still claimed he had no idea. He had not given my sister another thought once he quit seeing her. He said he did not know we were related. Again, I believe he was being sincere.

So I’m stuck. I like the guy, I even met his family and they were great. My daughter’s opinion weighs on me some, and since I don’t know the guy real well I can’t tell for certain if he’s being truthful. It’s hard for me to trust men due to past failed relationships (due to them lying, cheating, etc.) But I also feel I need to take the chance sometime or I’ll never find anyone. My gut is a mess. I don't know what it's saying.

So do I keep seeing him or call it quits? I’m very torn.
