Very interesting thread, very wise and compassionate replies.
First, let every single one of you be aware that it could happen to you. Whether or not you remain married has to do with your level of committment to the marriage to begin with.
I know what it is like to love someone who I couldn't be with, someone who I knew well enough to be way past the fantasy. I never imagined he was 'perfect', I just loved his very presence. God knows I have had enough problems with Mr Isla,enough to have made weaker women bail long ago, but what made all the difference is the fact that he is the father of my children. There was a time when I would have been totally justified in divorcing him, but I didn't do it. I had been isolated for so long that I didn't have any friends, and I didn't want to be alone. Looking back, I guess that was a good thing.
Telling the other person of my feelings helped me to move on. It was a relief and I don't regret it. I'm not quite sure what it did or didn't do for him, but I hope he has learned and been blessed by the experience as I have. I have never been able to figure out if he loved me or not, but I have come to grips with that fact that in this lifetime, it doesn't really matter.
I'm not about to judge anyone here. The heart has mysterious ways... love is a strange and beautiful thing. The real issues are about committment, honesty, and willingness to grow together. Mr Isla and I have that, although I have to admit I could sometimes do without the honesty part. I always wanted to be 'the love of someone's life' and instead I am the lifepartner and mother of someone's children. There are no pink fluffy clouds surrounding me or daisy chains at my feet... I have learned that love can be someone taking out the trash when it is his turn to. Love is knowing that someone has washed your underwear, checked the air in your tires, or made your favorite meal. <shrug> Will Mr Isla feel the same things I have felt for someone else? Maybe. I know he has been infatuated several times, but I wasn't just infatuated. If it happens and the kids are grown, I'll let him go. One of two things will happen: He will be happy with 'the love of his life' and I will be happy for him OR B: He will decide/realize that I was the love of his life all along and come back to me. I win either way.
Hmmmmm. That was long and rambling.... Gee, thanks Compuwiz.... I didn't realize I need to get that out.
edit: I guess if this post has a point it is that love is about the little things you do for eachother every day. That is better than anything else, IMHO.
