I have a DS with my ex husband. DS is 2.5 the arrangement we currently have is ex has him for a full day approx 10 hours whilst I work (he is unable and unwilling to do any more than this due to work/family commitments)
Recently ex mentioned he might be starting to work ad hoc on his contact day with DS but would know in advance. He suggested leaving DS with his dm or other family for the day. Nothing more was said. It then came about that ex's family are moving 300 miles away this summer so if that happens he won't have anyone to leave DS with..... except his gf.
I have posted before about his girlfriend, sending me weird and abusive messages and the part ex played in it. I have suspicions that ex has started this ad hoc work and is leaving DS with his gf, so she is in charge of him and their baby they have together for god knows how long.
If I ask him about it he will straight up deny it - but the whole thing makes me really uncomfortable given the (recent) history with the girlfriend. AIBU? What do I do?
