I wasn't sure whether to post or not...as it might not be at all relevant, but the thread made me think of a work colleague of mine who was in a really similar situation about four years ago.
She left her husband of 8 or 9 years and dad to two girls. Wasn't feeling the "corrrrr" factor, only man she'd been with, wasn't feeling "fufilled"...ect.
She said she loved him in a maternal way, and knew he was a really good guy and dad, but felt she would be happier and fufilled with someone who made her feel the sparks again.
fast forward four years.... she is finding that there are not as many dashing/romantic/exciting handsome/witty/stable mid-thirty year old men interested in a thirty year old woman with two kids and baggage as she had imagined.
The "available" guys who she's dated initially look like they will provide that "corrr factor", as you put it, have later turned out to have been married (and just looking for some on the side), or really financially unstable (and hoping she would be a bit of a meal ticket) or just plain flaky jerks.
or... friends would match her up with guys who were really nice and kind and good with kids, but who were struggling and broken inside because their wives had left them looking for something or someone else more exciting. These guys were usually obviously still not over their last relationship, but were out there dating because friends and family said they should be.
she is now currently involved with a guy who is married, he hasn't been completely honest about a lot of things- and she knows he isn't a prince but seems to be with him just to stave off boredom.
Is she more fufilled now than she was before? I haven't asked. Maybe she is. At least she has "the hope" that there is a guy out there she will meet who will meet all her needs... maybe just having the opportunity to have that hope is better than what she had before.
sorry for the ramble- my point is that to her "feeling fufilled" meant finding someone new who had all these fantastic qualities and made her knees weak.. and finding that just hasn't been as easy as she thought (and she is a very attractive blonde with great tits to boot..)
just think it all through before you do something that can't be undone. I hope it all works out for you...
