Hiya Gem ...
Ohhhh honey, Your really going through it at the moment arn't you chick.. I know what you mean about needing a hug belive me!!!
It seems to me like your OH is feeling a little un-nerved and doesn't know how to be around little harry... does he come from a family with lots of children?? If not then this could explain some of his strange behaviour.
Try and get him round soon, sit down and talk to him .... Ask him whats wrong and see whats bothering him ... if anything at all (could just be stress at work?)
When he has had his say, tell him about how your feeling and why ...
Babies take alot of getting used to and each party has his/her own way with ajusting to the change of having someone else in there lives... Belive me myself and my partner haven't been together long and we need to do the same, this baby is wanted but change isn't always easy ....
If you don't feel you can talk about it, write it down for him... That's what i do sometimes either in an e-mail or a letter... But thats just me.
Sorry your feeling like this at the moment, and i hope what i've said can help you in someway, ... If you ever need to chat P.M me..
Take care, Love and best wishes
Imogen+Bean
