Y'all Life is Too Short and Idk What To Do. Like This is the Equivalent of a Long Lost Ex Coming Back With a Ring After You Just Started Getting Serious With Another Guy in a Sitcom

This is what I wrote to my ex first

and then this is what he came back with

I dunno what to do. I been worried for a week, and I have been talking to another guy for almost 8 months. Problem being he hasn't asked me to be his girlfriend yet. Says he's not ready for a relationship, but we're damn near already in one, its just missing the title. He said there's been about 3 times he almost asked but didn't think it was the right decision. I told myself that I'll give him until we reach a year because I understand what he's going through but at some point I need you to know you want to commit to me...but my ex wants to see me at the end of may before he leaves for the reserves. That he wants to marry me. I'm just so so lost.
