FMIL has upset DP as she's sent a text asking when will we come up to visit during the summer holidays so she can see her DGCs - DSSs are 13 & 6, DD is not quite 12 wks.
I'll just try to state the facts:
FMIL is 75, but very active. She lives about 300 miles away from us and has visited us by coming down on the bus a few times before - we have invited her down to visit again, but she keeps making comments about how nice it would be for DP's nieces (who live near her) to meet their new baby cousin.
We currently have no car. Public transport would be impossible with DSSs and DD in her pram (journey by train takes about 6 1/2 hrs with 2-3 major connections depending on route taken). FMIL suggested hiring a car and said she would give us the money for it but we can't because DP has no credit card, I have no driving licence, and we're not married yet (could hire if my credit card had same surname as DP). We've told her this, but she's taking it as if we're being deliberately obstructive.
DD is EBF & borderline high needs. Even if we had a car right now, we'd end up having to stop regularly and for a substantial amount of time for me to feed DD.
DP has PTSD following a head injury from an attack 3 1/2 years ago which means he has a short temper and a low tolerance for DD's cries when she kicks off - I don't think he trusts himself to drive safely on the motorway if DD started crying and we had a distance to go before he could come safely off the road. Also, wouldn't want a massive cleaning bill if DD manages a projectile vomit or poo in a hire car.
There's only 1 week that would be possible for us to make the journey due to immunisations and hospital appointments for DD, which would be August bank holiday week - cue a doubling of travel costs if w did do public transport.
DP is upset (so is getting a bit ratty - remember, short temper from PTSD) that his DM is upset over this and is trying to make her see that it really isn't that easy for us to travel. She currently not answering her phone so he thinks she might be sulking. We know and appreciate that she's desperate to see her DGC, and especially DD for the second time (she came down for a weekend when DD was 2 wks) and we'd really love to go visit all of them, but we can't see how it's humanely possible.
I'm considering sending FSIL a message on FB to see if she can help get FMIL to see why we can't travel up. Would this be a good idea?
Advice anyone?
