Husband rant.

So we've been on and off for the past month (not my choice) his been coming and going as he pleases and last time I saw him he walked out on me and his 6 month old daughter he refers to 'that' or 'it' at 2am in the morning almost a week ago over a argument we had 2 years ago! He hasn't spoken to me won't answer my calls and made it clear he wants a divorce. He moved back to his mums whose been supportive of ME as she can't believe what his doing. So I decided to move 30 minutes away to escape it all after all the things his done to me I feel like I should walk away for good but I can't help but be so deeply depressed about it all
