Seems unlikely in my case, my H wouldn't admit that he'd made a mistake even if he realised it. Which means we could both go on to meet new partners (he already has) and be reasonably happy although without the whole family together can you really be 100% happy? I don't think so and strangely when he left my H said exactly that, that he'd never be totally happy without the family together, so why leave? Only he knows the answer to that one.
Anyone out there who's remarried and happier? I thin we'd all be interested to hear from you.
