I think the crucial crux of a marriage is to give and take. Having his close relatives over is only a yearly event, if only you could tolerate and compromise then it will actually make your husband a very proud man to have an understanding wife like you. However, if you constantly put on a black face and argues with him when they are around is just a total put off for your husband as you are very well aware that Guys ego is very important, and especially in front of his relatives.

And not letting him touch you because he wants a second child is another put off, it doesnt mean that when you want to have children only you both can embrace each other and have intimacy. Guys need physical touch, girls need emotional support... by moving out, what do you expect your husband to do? It will only create a barrier and allow third party to creep in.
