Feeling so annoyed.

Right my husband. In total been together for 7 years, we are currently living with my Mum as we are saving up for a house. I am putting my money away each month and he is saying i cant afford it this week so doesnt pay in so annoying me. he goes to his friends after work and doesnt tell me. spends his night in bed when he comes in. never spending time with me. this morning our one day off together and he has come to the shop with me never spoke to me the whole time and has been in bed all that time since. i went upstairs and he just says he is bored. it is pissing me off loads now! he is just acting like a child. he says he hates his job i said well i cant afford to keep you so grin and bare it, he says if you ever get pregnant you arent taking a year of maternity leave then . we have been TTC for 7 years. it is all my fault so its just a kick in the teeth why is he being such a tit????
