Long time lurker, first time poster and hoping for some sage advice. Single parent to primary age sprogs, working full time, going through divorce and still bailing out my ex on a regular basis (money sadly a big reason why we're not together any more.) Ex - MIL booked in a trip months ago to take DS out to a show in their home town in a few weeks. Today she asked me if I could drop DS half way on the Friday night - thing is it's a 2 hour 100 mile round trip on the motorway at rush hour with DD in the back too and I'm haemorrhaging money at the mo with no contributions from ex (who incidentally can't drive). I am pretty sure ex MIL and FIL willl drive DS back on the Sunday but I didn't ask for this treat (as lovely as it is) and I'm sure in most situations it would be the ex who should do this sort of mission but it won't happen). By Friday I'm normally so freaking tired - I'm already dreading the journey and think it's unfair I have to keep doing all the ferrying around. AIBU to ask for contributions to petrol (from MIL or ex) or should I just suck it up and deal with it? Worried I'll sound selfish or stingey. Help!
