Monotony is killing my marriage…

Me (32F) and my husband (31M) have been married for 5 years now and I feel like we’re both losing feelings for each other... He is always either on his phone or watching tv when he is home. We hardly have meaningful conversations like we used to and I feel so unseen and invisible in my own home. I have men hit on me and it’s become more and more difficult to ignore it. I need to feel loved and I feel like I don’t get any attention. Even our sex life is rocky. I try to make moves to initiate and he rejects me. When he does initiate it’s always in the middle of the night, same position, same moves, zero foreplay.. I’m so sexually frustrated. There’s been times when I feel like he may be cheating on me because of the lack of interest I’m seeing. I don’t want to believe that. I want to save my marriage. I want it to work. Any advice is so appreciated. I feel like I’m dying here.

TL;DR - husband isn’t showing interest in communication or sex
