Divorce or not...

After a few arguments recently and since we found out I'm pregnant my husband decided to leave the house and wanting a divorce. He says he loves me and always will but thinks it's best for both of us to get divorced... i don't want to go into detail but I convinced him to go to a counsellor with me before making a decision he might regret. We're married for 10 months now and he said he's not sure if the counselling will change his mind. I understand he's panicking because of the baby. It wasn't planned but we both decided to keep it and we were happy about it. We're both young he's 21 and I'm 24.

Any tips on what to say and do tomorrow to make him realise there are other ways to handle this situation?
