Husband drama

Me and my husband have 2 children.. oldest is 3.. she goes to pre school.. so my husband is going back home to another country for 3 weeks.. he hasn't been in 2 years.. we has a family can't go because we can't afford to.. i want him to go but the problem is the dates of when he goes.. my daughter has holiday terms.. so i was planning to go to my parents for easter.. they live 6 hrs away by car.. so basically i'll come back home and be alone for 3 weeks.. he want's me to stay at my parents and our daughter miss 3 weeks of pre school.. i'm not happy about that.. in fact i'm not happy about any of this but it's too expensive to go earlier.. i have no friends to rely on.. i don't have anyone here.. i live 3 flats up and no lift.. i'm annoyed at him and he's annoyed at me.. i haven't said anything but if i do.. i know we will have a massive argument.. i can feel it and i really don't want to.. it's never concluded well. Thanks ladies.. i suppose i'm just embrassed by being alone.. and what do i say to the nursery?
