Relationship ended over depression meds?

Recently I had my s/o of three years end it because they felt more like a “caretaker” than a partner. I was diagnosed with non combat ptsd and general anxiety and the depression that comes with that. I have been on lexapro for a little under two years. In those two years it has been extremely difficult to be intimate with them, both from trauma and lack of sex drive from the meds. I am angry and devastated and feel like I have no recourse of action. I have had another three year engagement end in 2012, and this is bringing up all those same insecurities and fears. They said it may be just a break, or it could be forever. They said they would always love me but we both “need to get better for ourselves”. That was dec 9th, since then I have had to move back in with my mom, was passed over for a promotion, and lost my main means of transportation. They haven’t been in contact with me aside from the occasional hi, and I feel like I am trapped between moving on and hoping they will decide they want to forget the whole mess and move forward.
