FIrst off - I'm really happy that you have found a wonderful woman to spend the rest of your life with. As for your ex - she would, of course, find fault. She sounds like an unhappy camper. No woman would ever be good enough for her kids. I'm glad your kids are not influenced by that bad attitude.
I went for the total opposite "type" of my husband. He was skinny, blonde, hyper, bad temper, undereducated etc. Mr Right (of over 8 years now) is stockier, dark curly hair, calm and gentle and has a masters. Could not be more different - but that''s what I needed.
