Search Results: not over his exes

firstly
me and my boyfriend been dating for over a year
my height - 5ft1
his height - 6ft4
apparently all his other exes were taller than me so im the shortest girl he's been with (not all of them was tall but they were taller than me like his previous one would prob be 5ft4 and his other one would probably be 5ft10 or something)
so anyway he keeps calling me a midget
he would joke around with me and saying "aw you're a midget"
and i said "f off.. im not that short. I've seen way shorter girls"
and he goes "its alright.. its cute. you're cute. i like short girls"
and i said "your exes are taller than me"
and he goes "yea i dont like tall girls. i like short girls. theyre cute. like you. with tiny legs"
and he starts laughing.
wtf?
am i supposed to be offended?
does he not find me attractive?
why would he be with me if all his exes were taller than me? wouldn't he find someone around his height or something? since he's calling me midget -_-

I've been seeing a guy for two months now and I am a single mom. A couple of weeks ago him and I had a talk and he basically said he doesn't want to make it official yet because he's got a lot going on (he races pro UTV, goes to school and works) and said he doesn't want to make promises to me he can't keep. He said I'm not in the friend zone at all, but that I'm in more of a "holding zone" until he figures out his life. He's also hesitant because he's had a lot of loss in his life and been screwed over by exes and is scared (haven't we all?), so he wants to take it slow. He also feels like I would try to get him to stop racing, even though I told him I wouldn't. I was a little disappointed, but decided to stick with hanging a few days a week and taking it slower. He's not using me at all. We've only had sex twice, and he pays for things we do together and drives us places. I've met a lot of his family and friends and he has met my parents, so he's not keeping us "hidden". He texts me everyday, good morning texts in the morning, and shares a lot of details about his life with me. Herein lies the problem. He has two boys (2 and 3) and I have a daughter (2). I'm worried about the potential of any of us getting attached to each other and him deciding not to go any further with this. My daughter is starting to talk about him a lot and ask for him when he's not around, she really likes him. His boys are really starting to like me to, hold my hand places and stuff. Anyone been in a similar situation? Any advice? Give it more time to grow or end it?
