Don't want to spend on me

Since I'm preggo and a SATH wife I don't feel like myself anymore. I rarely put on makeup now and don't even dress up either. I've always been the social and well dressed person but I've become the complete opposite now. I still window shop and look at clothes and makeup online but because I don't work I can't get myself to buy anything for me. As much as I want that beautiful dress or those shoes I just wouldn't feel right because I'm not contributing to our finances. Maybe this thinking is wrong but I feel guilty spending. My partner doesn't buy me much either but hasn't said I could go ahead and spend... he buys here and there only but when he does...he really spends. I just feel that because our income is limited now I can't buy nice things for me, until I have this baby and make money again I will just continue to dream away my fantasy closet and the fashionista I once was.
