My ex and I have been split up for 3 years, we have 4 children and he left me when I was pregnant with the youngest, he didn’t bother seeing them for 3 years and seen them about 3 times in that time. About 6 months ago he contacted me and said he wanted to start seeing them again regularly and be a dad, we spoke and he basically told me he wants to see them every other weekend for the day, so twice a month, at first I allowed the situation but as time has gone on I’m starting to feel resentful about it, he has no home to take them to so can only come here to see them, would it be unreasonable to tell him he needs to step up and be a proper dad and see them more or not to bother? It’s really not been easy raising 4 children alone and my oldest two have additional needs so even harder and all he wants to do is take them to the park twice a month. Should I be insisting on weekly visits?
