DP and his ex used to live about a 10-15minute walk away from each other so travel for contact of their 4 yr old was never an issue. About a yr ago his ex moved 10 or so miles away, which doesn't sound far but since both rely on public transport, is actually about a 40 minute bus journey - buses really suck here! She expected him to do all transport which was unfair (IMO) but he did it as it was the only way he was able to see his son. We've now moved another 20 miles (a 50 min train journey) in the opposite direction and when he spoke to her about it before moving, she agreed she'd meet in the place they used to live so they'd share travelling. Unfortunately, that's not happened and DP faces huge arguments if he tries sticking to the agreement of meeting halfway(ish) instead of taking him / picking him up directly from her flat. She says it was our choice to move (fair enough) but fails to see it was her choice to move in the first place!
Aibu to expect her to help with transport? If we were the only ones that moved I could understand it but at the end of the day she moved too so IMO should help! Yesterday she started shouting and swearing at DP as he said he'd drop him back in the middle tomorrow (like originally agreed) instead of flat! We would never ever expect her to come all the way here but she thinks it's DP's duty to go all the way to her.
