I separated from XH a year ago (due to his infidelity, emotional & financial abuse and general shitness). Things had been fairly amicable until a couple of weeks ago when he found out I'm seeing someone. He then decided he wanted us to get back together, claimed he had changed, would only ever love me, etc. I made it clear there would be no reconciliation, he became increasingly desperate, culminating in him turning up at my house on Friday evening, forcing entry and refusing to leave. I called the police and they made him leave.
Last night I got a text from him saying he was leaving the country, and didn't know if/when he would be back. He said he would come back immediately if I would take him back.
Since we separated he has seen DC weekly, he hasn't wanted them for any longer than one night a week but it has been regular, they love him very much and have enjoyed their time with him.
I don't know how to explain to them that he has gone and I don't know when he'll be back. They are 7 & 6 and found the split difficult to cope with, it seems like they've only just adapted to how things were and now everything has changed again.
