Heartbroken and needing help!

[irishblessings]

Just got back from dinner with the kids.
H calls and says that he is now going to be staying with a friend (younger) until he can get on his feet financially.
Says the kids are ok with him joining us for dinner if it's ok with me. So I say sure.
Have decent dinner / kids begin to leave / I get my things to leave after I pay bill.
H tries to follow me to the car - says I wanna give you some money for dinner but I didn't want to do it in front of the kids. I said not necessary. He says do we have anything else to talk about - I say I don't think so. He says ok and walks away.
I leave and cry the whole way home.
This cannot really be my life! (just venting - I know it is)
