I really feel bad as we aren't getting any time.I get my weekly off on Thursday n Friday,those are the only days we get to talk to each other. But unfortunately he got some work n he went out station for 3 days. I really feel bad and sad where is our relationship going.The spice is missing. The last we had sex was 6months ago 😓 Can anybody please tell me what should i do as I really love him. I also wanna plan something for his birthday but we don't have a place of our own.Please suggest me something..
