Confused and lonely

Long story short. My wife and I have been together for 11 plus years (same sex couple) lately I have been feeling unwanted when I ask for us time she is constantly on her phone. I don't think theres any cheating going on I trust her 100% I just feel like im begging for her attention nowadays its sucks because I have noone to talk to I have no family nor friends. What should I do to make her realize it takes 2 to make a marriage work not just me. I've told her that I'm lonely and I miss her but nothing is helping.. Im so scared that maybe she dont find me attractive anymore Ive gained a little weight as many have during the pandemic. I feel like she doesn't want me anymore or am I over thinking it?
