Really need help marriage issues

Hello I need some guidance and advice. Shirt history been with my wife for almost 19 yrs married for 10 yrs we share 5 children. Married the girl next door. Last year we started having extreme issues fighting was bad. She told me she wanted to separate and see other people and had fantasies about a man across the street. We worked through that and now she claims it was to make me angry. I dont believe her and now she is distant , doesnt touch me ( sex 2 months ago before was 4 months. Barely kisses me and is constantly on her work phone and talking to work friends. I just want to hear some thoughts on if my worries that sue is done and ready for me go. She avoids talking to me about our issues and claims she loves me and only me but the second I confront her she deflects and brings up any mistake I ever made. I just want to he happy and feel loved, needed and wanted but she says I'm the issue and I need to fight for her and prove I love her. I do that's the issue I tell her constantly I bed for attention and affection but it never happens. I love her but I dont think she loves me anymore. Please help with advice or thoughts on this situation I need it. Insufferable from severe depression and it is not helping me at all. Yes I am in counseling and medicated ( therapist will not give me martial advice says that is for another type of therapist. just need some thought please I am lost and afraid.
