Thank you everyone for listening and replying. Your answers all made me feel not so alone. I am looking after my seven year old on my own and at times it does get a bit isolating. Thank you for taking time to help me.
MonayOldCow: you made me laugh - yes that was my birthday present, crazy right?
AtrociousCircumstances, you are spot on I do think he has planned his holiday with his daughter all along and have been pretending to be busy so he can "justify" his absence.
LanaDReye I can't agree with you more because I am totally unhappy and simply find what happened so unacceptable.
ICESTAR your words really hit home, it doesn't matter who he went with, the fact he has claimed to be too busy to come home but yet went away on holiday with his daughter really made me feel hurt.
TheNaze73 Good point! Yes of course I am jealous of his daughter it is natural, she gets everything, as she should, from business class flights (if I go to see boyfriend in the uk I pay my own way economy) to £350 jeans and diamonds for her birthday - hard not to feel jealous when my birthday present is a photo of him on holiday :) But I am also a grown up woman with my own son and totally independent with my own income which helps in me contributing towards the relationship financially thus the giving helps in assuaging my feelings of jealousy. However, it really doesn't matter who he has gone with in this occasion, I would still be livid.
SleepingTiger, you are right we have communication issues. I haven't spoken to him for days and I still don't know what I am going to do about us.
Aquamarine1029: Yes I must let go of my resentment, I am hurting only me. Well said, thank you.
We live together in Thailand and own property together here half of which I have paid for. Breaking up and moving out needs planning, not impossible but just hard. I will chew on what everyone said and practice more letting go and see how I feel in the coming days.
Thank you once again for taking time to reply.
