Heart break venting

So few months ago I became a single mom of 3 kids 6 ,2 and 1

Had a what i thought be the one this was it. Built my family loved him like no other.

He got into drugs

Things got bad at the end I had to get a restrainging order due to his anger.

Havent talk to him in months nor the kids have been hard on the oldest.

Breaks my heart I miss him

And now I have to get rid of my dog possible what's breaking my heart

At the moment there dad is little over a week sober. I will be extended my order next month once court date is up just all breaking my heart for me for the kids

I dont regret being with him ect I dont regret putting my children first and just hope he can get the help he needs to one day be back In the kids life
