The one that got away 💔

Ladies is there ever someone who has been in your life but you had to walk away? If so let me tell you this doozy, I met this guy when my son was 4-5 months old online I was feeling lonely & down because I had left My son's father and was back at my parent's house and they were very I told you this was going to happen instead of reassure me things were going to be okay. Well, I downloaded a dating app and got a lot of different guys hitting me up, but I still couldn't fill that void of loneliness & didn't care would ignore the messages and just read them which yes it seems rude, but I was not in the best state of mind at the time.Anyways, fast forward a couple weeks and this guy sent me a message I reply we joke around and get a long very well, we messaged on and off for a couple months then Me & my son's father decided to try and get back together regardless of what had happened in the past with us, I stop talking to the guy I met online completely, but I yearn for that emotional connection..so I start talking back to him again me and my son's father were more or less together but living apart and we had our differences.I told the man straight up what was going on in my life he understood since he was separated and had 3 kids of his own with two separate women. He told me we could be friends, but I could tell he wanted more from me & I could not give that to him at all we were like best friends as hell we'd talk about everything and anything we shared so much together, but I was still with my son's father at the time we were just not living together and he didn't know about my friendship with this guy. Well to cut a long story short, I decided last year during November that I had to cut off this on going relationship with my male friend who seemed more than my friend tbh even though we did nothing physical he was the first one I wanted to tell anything to about my day, my hopes, my dreams. I broke the news to him that we had to stop talking, he asked why I told him the truth I can't give you what you need I don't want a relationship he was heart broken as I was I for letting it get this far, but I never led him on he knew what it was we both decided it was best to distance ourselves.I found out during Thanksgiving that I was pregnant with my 2nd child from the same man who I had my first baby with, but I still yearned for that connection with that friend so I asked him how he was it had been a whole 3 days since we had talked he said he felt like his world was tumbling down & I felt terrible it was all my fault 😖💔 anyway we started talking again till January I knew I couldn't keep this going on, so I told him my phone was going to be cut off & that I would reach him when I had it back on which I never did and now me and my son's father got back together, we started shopping for our daughter we got our own place and I still think about this man and how I can go about giving him and getting closure from this situation or if I should just leave him and the past alone. I miss him every single day and sometimes I think it was a mistake getting back with my children's father 😕 In the back of my head it's always like he would of never treated me like this 🙁 but I really never deserved a man like that I just don't know how to move on from this I said I just wanted to be friends because of feelings for my children's father, but it was a lie I had so much feelings so many for him and it eats me up inside that I will always have this what if in the back of my head, but we were both in two different places in our lives he is 6 years older and had his shit together I didn't at the time..any advice ladies?
