separated but still having sex?

Rebecca

so my husband and I have been separated for 7wks now and the last few weeks we've been having sex. is this ok to do? I mean I feel guilty but not bc we are still married he just don't live her.. we have a 5yr old and a almost 2 yr old and as of this past week after I take him for child support and custody he says he'd like to work things out.. I'm so lost as to what to do bc he hasn't done anything I've said needed to be done b4 he j cones bk into our lives completely. so any advice as to is it ok to continue having sex with him and do I believe him and try and work things out? He cheated on me over sexting/ phone and this was the second time.
