Was seeing a man for around 6 months. He is divorced, his wife left the family home and he stayed with his two children. He actually has three kids but one is away at uni.
The relationship between us was really good, we talked, had loads in common, saw each other regularly and he was kind and considerate towards me. I noticed early on however that he spoke much more about his youngest child than the other two. Eldest two are girls, the youngest a boy. He is extremely proud of the boy, goes on about him all the time, bigs him up constantly and takes great delight in sharing his acheivements with me. The boy is 10. He occasionally mentions the eldest child at uni but rarely talks about the middle child who lives with him. When I went to visit his house one night I noticed that the boy had trophys and certificates and photos everywhere. There was very little evidence of the middle child even existing! He showed me around his house. It was very nice but it also struck me that the young boy had the large, attic bedroom and it was all kitted out in the latest gadgets and new furniture. The middle child (girl aged 16) was in a smaller bedroom with nothing more than a bed and a chest of drawers and an old TV/DVD player combi.
Anyway two months ago I met his youngest children for the first time when he invited me around to dinner. The young boy was showcased ALL night and it was constant "hey show her how you do -- and show her - oh and watch him do ---- " it got a bit tiresome after a bit tbh but I stayed polite and made a fuss of the lad (who to be fair seemed like a lovely boy if not a little full of himself!). The 16 year old seemed quite shy but made an appearance to be polite. She said hello etc and she seemed lovely. DP however wasn't very nice to her at all. He took the piss out of her hair, asked her if her room was tidy yet and laughed when the young lad started ripping the piss out of her clothes. DP then turned around to me and said "she's a wierd one, all emo and stuff" to which she replied "actually, it's called not being a sheep and I'm not emo, that was 5 years ago" DP and his son then laughed together and she sighed and went upstairs. 5 minutes later DP went upstairs, the boy followed with great delight and then came running back downstairs to tell me that his sister was in a world of trouble for showing her dad up and was in the process of being told off and was crying!!!! 
Anyway a week later we went out with my son. He was ok at first but then started going on to my son about joining his rugby club and questioned him when he said he didn't like rugby. He then said "ah DS will toughen you up when you meet him". I told him that DS didn't need toughening up and he was fine as he was etc. He made out I was over-reacting and taking him too seriously.
I gave it one more chance involving the kids meeting each other (stupid I know). This again started off ok, they were at the park, boys running off going wild and his poor DD tagging along behind us. I tried to involve her by asking what she was listening to on her ipod and he interupted her answer by telling me "oh you don't want to know!" he then told her off for being ignorent and ordered that she put the ipod away. Her eyes filled up and he dragged her aside and had a major go at her about showing him up and mentioned she had been warned before they came out. I was feeling really uncomfortable at this point and started to make excuses to leave but the kids were hungry and I agreed to get something to eat. His ds then started going on about DS being a total wuss and that he nearly had him crying etc. I said "well that isn't nice, is it?" to which DP burst in with "You wern't nearly crying, were you?! he's a tough lad! he'll be catching up to you soon DS, he might have you crying one day!" ???? DP took the lads to the toilet and I was left with his DD. She said to me at this point " you'll hate him too if you spend enough time with him". She said it in a jokey way but I think she meant it. Made me wonder what her mother had gone through.
I apologised to DS for the whole thing later and I've not replied to this man's calls or texts since. I'm so angry for that poor girl and wonder what the hell he did to his wife. How on earth do you get over a disaster like this and get back into dating?? This was the first "relationship" I had since the breakup of my marriage and tbh it's put me right off.
