Livelife,
Welcome to SR. This place has safed my life a few times, they make you feel loved and secure here.
The man you are talking about is NOT the man you love it is the addict talking. The one you love is nowhere in sight right now. He is threating you and your kids, that scares me. Please talk to the police and file a report, you don't have to press charges at this time. Just get it on record, so if the time comes that you need to take other steps to protect you there is a record of what is happening. If he should, god forbid, do something there is a record of the threats and it will make it easier for an arrest.
If you don't do this for you do it for your kids, they need to be protected also. It is a shame that they can't go out and play because of this man. I wouldn't let them out of my sight at this time.
I will pray for you and your kids to stay safe and to be protected for this addict. Hopefully the man you love comes back in the picture in the future
