birthday present

Ba
it's almost my birthday and i got spoiled with a iphone se in pink 🙂 i'm happy about it my partner actually wanted me to have one and i'm grateful cause now i can work and organize my self as before instead of using the pic and migrating stuff from other platforms. 
However my concerns come with the value of the device it self it's still expensive to get one and i wanted to use the money in something we would both enjoy and for the baby things i could get for her and for the house... as commented before... we don't really have much or earn much for certain luxuries.. i feel guilty some times to get my self spoiled. But i just want to have things ready for her and that my partner doesn't need to sweat either :( so although i love my new device i don't feel i'm enjoying it fully out of guilt. 
is this ridiculous of me?Â
