Therapy

I've typed and re-typed a post about 20 times at this point making sure it follows the rules lol. Just recently found this sub and I've never felt so heard before. I really thought I've been losing my mind, but turns out I'm not the only one.

I (29M NT) am about at my breaking point with my wife (30F DX). We have been together for 5 years, married for 4. Honestly most things have been really good. However a lot of stuff the last year has been steadily declining. It really feels like the masking stage has completely fallen away and Im seeing her for who she truly is. Sex life is almost gone. I'm lucky if get anything once a week. She barely takes care of herself. Her career and phone have taken over her life. It feels like our son and I have just fallen to the way side.

My question is, are there couples therapy success stories? Or is it even worth it? I know it's a hard question to answer because everyone is different. But I'd like to hear people's experiences positive or negative.

She has been receptive to our talks and has permanently made some changes, but its starting to feel like it's on repeat with me crying and begging for the littlest changes. I did make a post on the weekly ven for more details.

EDIT: forgot to add she is on Adderall and has been for the last 2 years.
