It will be my only free weekend from now until I go on honeymoon in June - DH and I very busy up until that (finishing professional qualification/ working/children etc). It's MIL's birthday so a part of me feels bad putting up this boundary but have offered alternative dates this month or when we get back in July.
We will also have to organise their whole weekend (hotels/travel/cabs etc) so it's yet another thing for us to do when I am feeling stressed. We always do the travelling to them (6 hours), the only time they have travelled to us was for our wedding. I study for a professional qualification (think healthcare) full time and work evenings and weekends. I need one weekend to gather myself before we go away.
AIBU or is it fair enough?
