LOSE WEIGHT OR HES LEAVING⁉️‼️😩😕😥

Last night as I was talking about one of the new OITNB episodes and changing into my pjs he interrupted me and said, "I think you should start walking". I was taken aback because this came out of nowhere. So I replied, "okay i can do that". He then went on and said, "yeah I just don't want to lose the spark between us". I couldn't help but feel extremely insecure. As I stood there naked, jiggly, with stretch marks, and already insecure the man that I fell in love with spoke on my flaw that I desperately wanted ppl to ignore. He proceed to have sex with me but couldn't maintain his erection 😩 I felt humiliated! As he rolled over and didn't finish I cried on the bathroom until he fell asleep. 

I want to have the "are you losing interest in me" conversation but I am afraid of hearing the truth. I am often called dramatic and analytical when it comes to overly sensitive topics for me. 

Should I have this conversation with him? Should I listen to his advice and lose the weight in order to save my relationship? Any advice would help me...

Sincerely, 

A confused woman
