My boyfriend and I have been together for 5 months and we just moved in together. Ever since then things have been different: we barely have sex or fool around, he's lazier when it comes to things like cooking and housework, and I feel like he's constantly picking on me. At night he won't even come to bed with me. It hurts me feelings and it honestly feels like he moved in just to make things easier (he's a single dad), its like I'm just here to do all the work while he has all the fun. Last night I asked him for a kiss and he wouldn't even kiss me. I went to bed crying. He finally came in and I asked him if I did something to upset him and he said no. Sometimes I swear it's like I annoy him, I feel like I'm walking on eggshells. Any advice?
