DH is leaving me for someone else

[Terrorteens]

My dh is leaving me for another woman, we have had probs for a while but where slowly working through it, we had a row lastnight and things came to a head and he told me he's met someone else at work. We have 3 kids and I am terrified. I still love him dearly and thought we was getting back on track do I wait for him to see sense or is it really over. If it wasn't for the kids I'd let him go but I've got to think of them. My parents live overseas I've no one I can turn to. My friends having the kids at the moment as he's coming home soon to collect some things and we need to get it out.
I need advise please what I need to do next.
Was posted on AIBU but was advised to post on here.

Since yesterday he as come to get his stuff don't know wheres he staying I keep asking about this woman but he stays silent. The kids are back home but I am a mess.

The only option that will make things better is to take control and hang on to your dignity. Consult a lawyer and the CAB, get all the facts about finance, housing etc, keep your contact with him to the absolute minimum (preferably email) and hold this thought at all times - if he suddenly decides he wants to come back to you, he is going to have to work for it. You are not prepared to have him back and just be grateful that you're not single, he is going to have to demonstrate to you that he has chosen to come back to you for better reasons just than not wanting to lose his home comforts.
