Emotional SO recovery

So my SO is in recovery has been for 2 months. He has been off of hard drugs for almost 2 years, but had picked up a DUI and now has also quit drinking and smoking weed. He has to go to counseling 3 times a week and take uas and what not. Anyways. We were supposed to get married. He canceled it. Yesterday he broke up with me( i am 7 months pregnant) today he came back from counseling and we talked it out. He said they told him hes at a sensitive time in his recovery and will most likely have a lot of negative thinking and we are not supposed to make any big decisions. I have been advised to go to ala-non meetings (not sure what that is) but thought id start here since im on glow all the time. So i guess. Does anyone know if these changes are normal? I have thought we were getting along great and now he says he has all these feelings and doesnt know if he wants this. I have never been a user of anything but weed. Im so lost and confused. Does he still love me? Does he really feel these things towards me :/
