Not feeling enough

Over the past few weeks I been battling depression I’m usually positive about having ms and moving forward but I been in a 5 year relationship and I found out about multiple females since last year in September there’s nothing worse then making someone whose already sick and trying feel lower than they already feel. He doesn’t know I know he’s applied for a apartment and he’s gonna leave me without explanation some people get ms and lose mobility but I’m still mobile I cook clean take care of my kids and bills I pull my weight more than anybody in this house sex hasn’t been a issue for me but he still does me wrong I feel like since I got sick he hasn’t taken me anywhere in 3 years I know it’s not just me in my feelings ready to just move on I can do bad all by myself
