Please hlelp me with a problem that is causing so much trouble?

i do not want to sound jealous in any way or form as i am not, but our friends have a daughter who is 7 years old, whwnever we go there she hugs and kisses my husband all the time and me just treats me like shes got to be nice because her parents have told her to be, its giving me a real complex as i am overweight and have a prob with my leg that makes it swell to twice its size., i dont know if she finds it scary and that this is why she is wary of me, or could it be the fact thst my husband adores kids and play fights all time with her where as me, i can take kids or leave them, love my own dearly but i cant go as far as to say i love kids in general, maybe i give out stay away signals i dont know, but i am always nice to her and talk to her etc, i just want to know that if she dislikes me so much, is it poss that a child so young could be trying to make as much fuss as poss of my husband to make me feel like an outcast, cos this is certainly what it feels like , and it makes my husband and i row as it gets to me as he never treated his own kids the same when that age, he never had ant time for them, we were there last night and it all really wonud me up, help please
