Hmmmmm - OK this one hits so close to home it's kinda scary.
Now - BF has never ASKED if I had an issue with him having friend on FB or elsewhere that he had a R with in the past - topic never came up. A little background though - he is friends with his DDs mom (they have been apart for 18 years) - matter of fact she and I are friends (in real life and on FB) and we just went to her place for a bit to change to our costumes on Saturday night.
Also, I have been spending a couple hours every Sunday sitting next to BF with his STBXW on the other side of him - and we give him grief while watching THEIR DS play. In both cases, the children are proof postive of a physical R if there ever were one, but I know that we are not normal - never professed to be though! ;) Shoot - his first W - from when he was a kid - tries to friend request him on FB and he ignores her - and I'm so dumb - I kinda feel sorry for her. WTF!! ;)
He also has a friend that IS on FB - I didn't know who she was - she was a friend from the 'old days' - and she came to one of his shows. I didn't know till just before that evening - that THEY had been FWB - matter of fact - as he put it - he wanted more - way back when - and she would never commit. I will admit - that gave me pause - but hell - it was 20 years ago - and I know who he is committed to now. She and I met - we got along great - and now we are also FB friends - and chat more than the two of them do. Weird - yeah - but it works for us. She even told him that I was the first girl she saw him with that she actually liked - besides herself! Ha ha ha
Now in your case - him being gone alot and all those things - yeah - if I were facing that - I might have more of an issue with it - but for me - BF is home with me all the time - he shows me everything on his FB, My Space - etc - whether I ask or not - lol - and I can get into everything if I wanted to (which I don't - no time for all that!) - so I don't have a problem with it. Plus - this gal - LOL well to say she is high maintenance would be an understatement - I think my BF is pretty damn happy that she wouldn't commit. ;)
So - I guess my answer to your question is this - if it makes you feel weird - and it bothers you - then you have every right to tell him that - and the two of you need to discuss it and try to meet somewhere in the middle. I suspect that he will never totally see it your way - and you won't see it his -but that's ok - compromise is not a bad word - it's just a fact of life.
Don't beat yourself up over no seven-second delay either honey - sure - there might have been a better way to phrase it - but damn - if you wanted him to know how you felt - you pretty much got that point across - huh??
Sorry for the ramble - guess I'm just trying to say that every one copes differently - things that might make you nuts don't bother me - and I'm sure things that send me over the edge - you'd look at me and say - Lynn - calm the F down!! ;) Same for you and your honey - but knowing how far you guys have come - I know this is just gonna be one of those things that once you work it through - it won't seem like such a big deal - KWIM??
Bottom line - talk to him - no need to grovel or say something you don't mean - just be honest - it's always the best way.
Love and hugs sweetie!
Lynn ;)
