I don’t know what to do.. 😣

Hey everyone, no judgement please! I’m a young mom, in the navy and I am now relocated on orders to be co-located near my soon to be ex husband and his family. During my time here (about a month so far) I have continued a long distance relationship with someone I met in Virginia, we’ve been together around 7 months. We had a great connection, it was completely unexpected. My child stays with her dad and I now visit more due to me being deployable and not having a consistent home/due to no bah from being separated/child custody issues. (Please don’t comment about me being an unfit mother or not capable of taking care of my child or not wanting to be apart of her life because I do!) well, so I am at a crossroads. The guy I am with in a LDR is not currently wanting to get married to colocate to be near eachother. I feel deeply in love with him. I want it so badly. But he says he doesnt know when the right time will be to get engaged and then married. My ex husband now also wants to try again and see where our relationship goes now that we’ve been apart for a long time. I have the opportunity to fix a broken marriage, (my feelings for him are gone almost completely, but I think they could maybe grow again if we both tried really hard.) or I could continue a relationship that has no “light at the end of the tunnel to be back together” even though I feel like I do love this man. What should I do?
