Do I Let Go, Or Give It One More Chance....

Hello All,
This is my first time posting anywhere about my husband's addiction. We have been married for almost 7 years and this year will be the first time I fully admitted his addiction to everyone around me. We have 3 beautiful children together and I am 8 months pregnant. He has put our family through more than I could even express here in 7 years. He is addicted to pain pills however has also struggles with drinking, and started with pot. When I was 8 months pregnant with our first he got a dui, then he lost his second job for stealing money for drugs, third job for stealing prescriptions from the dr he worked for and was prosecuted and put into a year long treatment program.
He has been through numerous programs and nothing has helped. Recently after thinking he was sober for a substantial amount of time I caught him attempting to buy drugs and made him leave, we have now been separated for almost 3 months. He chose to go to an in treatment rehab program and recently got out. He says he has changed and thanks God for sending him.
He currently lives with his parents is working on getting a job, staying clean and becoming the partner I deserve and father my children deserve. However since he has been home he has been on fb more than I think necessary, wrote a hurtful message to a family member about how he doesn't know what will happen with us but he is strong enough now to handle divorce and even joked about meeting someone else someday. He also added about 9 people he recently met in rehab, mostly women. He has never cheated on me and I don't believe he would however I find these things extremely disrespectful and hurtful. I have stuck by his side for almost 7 years and he has the audacity to joke about such things. Also as far as I can read and tell making friends with other new addicts is probably not best solution for long term sobriety. I am okay with people who have been clean a substantial amount of time but not other new recovering addicts. Well, he promised me he would quit communication and he also closed his fb. However just the other night checking his cell ph records I find he has communicated with them a least once since our conversation.
I am trying to practice detachment but this is difficult as I am 8 month pregnant and we have 3 children together. He tells me that he is changing but it is a process and he is working on changing the lying etc. I just don't know what is best for me right now, do I give him another chance or do I cut my losses and leave not wasting another year to 7 of my life not to mention making another extremely difficult time for my children. I am lucky they are very young now but it has been difficult still for them. I do not want to take him back and put them through this again. I feel I am just going on and on here but I have never spoken to anyone who has been through something similar so I am looking for other's experience's and any helpful advice.
Thank you for reading this
