Trying to conceive after a miscarriage

I have one child he is 3 it was hard to concieve with him i was conviced i couldnt have a baby we tried for 3 years and finally it happend but we split up when my son turned just shy of two because i found out he was cheating on me with his boss any who i found out i was pregnant with my new partner it happend kind of fast i had no problem conceiving this one so i was super excited but recently i had a miscarriage and i was devastated i wanted this baby so bad i have been having baby fever for a while now lol my partner was excited when i told him. he doesnt get to see his first son because his baby mother doesnt want him involved with her son because he went to jail so anyways i live in Arizona right now he lives in Mass so it kind of sucks right now but he would call me every day throught the day to check on us and contantly ask for stomach pictures and record the doctors appt so he could see what was going on even though he couldnt be here with me because of his open case. So he asked me if i would fly out there to have the baby so he could see the baby and spend time with the baby before i came back out here to az Recently i told him i lost the baby and he cried and was distant towards me he wouldnt respond to me when i called wouldnt answer my messages and i just felt like maybe he thought that it was my fault 😕 but he recently told me everytime he talks to me it makes him think about it so we was starting to be in a bad place but we are slowly getting better so anyways i go back home to RI to pick up my son from my sons father to bring him here to az and im going to be there for about 2 months before i come back here to az and he wants to try again any help on how to kind of make it easier for us to make it happen ?
