miss my relationship 😕

My two daughters father and I had a very bad break up back in May. I was 22wks pregnant at the time. We have gotten past everything and co-parent so well. Part of the reason we would fight is because I didn't think he paid enough attention to the kids (my 5yr old and our at the time 9mth old) Anyways since we have been apart he has become a very good Dad. He actually spends quality time with our kids. I love watching him be a Dad. We see each other almost everyday cuz I believe that children should see both their parents often no matter what the situation. Since being broke up we haven't crossed any lines. It's like we are best friends who have had two kids together. I don't want to lose that. I have no desire to date anyone. I honestly wouldn't trust another man around my daughters and I don't think I would be able to find a guy that agrees with the girls father being around as much as he is. I miss us but I don't think he does. I hate that my family is broken. I don't know whether I should fight for my family or let go.
