Sounds like a mid-life crisis man thing to me..'The grass is greener' syndrome - you said it yourself, 'she' was being nice and uber friendly while you were ranting at him, not that ranting was wrong, a woman sending flirty texts to a married man should have been nipped in the bud by him - but no, he felt flattered, same as now he thinks that instead of being happy with his lot, he's still 'attractive' to the opposite sex. And lets face it, you might be devastated, but you couldn't have been happy with the arguements after a while either You say you love him, which i can understand, you can't turn feelings off and on like a tap, BUT could you trust him again? You say that's lots of changes would have to be made if you were to get back together - would your husband be happy to move/change jobs etc - would you? If you think, and think honestly that you would always be suspicious, always worrying if it was going to happen again, then you'll give yourself ulcers with worry. Information is power - find out how you would stand financially if you were to part, and don't be afraid to ask questions, it's a relationship - two people - you shouldn't have to sit around waiting to see what he decides, you have a life, you'd love it to be with him, but you're not going to wait forever. Give him three months say, and if he's still undecided by then, well...you know what you must do - dress to kill and let him know what he's missing. Good luck
