A little bit of background. OH and I live together in a very happy relationship, we met about six months after his marriage broke down and I moved in six months later (I know really quick but we're not kids and didn't see the point of hanging around when we are very happy together). He has two children, boy and a girl, nearly 16 and 11. OH is very much into his sport which I don't generally mind, it does take up a lot of our spare time but it gives me down time to enjoy time with friends, catching up with personal stuff (I work long full time hours).
OH recently went abroad on a boys golfing trip, only 5 days and funded entirely by himself. No issues here. While he was abroad he entered a competition for a bit of a laugh with no intention of winning. A bit of a pitch and putt. He's ended up winning an all expenses paid, four day trip to Dubai to watch a golf competition final. Luxury flights, accommodation, meals paid for, you name it.
Fabulous! I get to go shopping in the Dubai malls while he watches the golf. No! He's decided to take his 15 year old son (who shares his love of golf - it would be wrong of me to miss this bit out). The reason being is that his mates would disown him if they thought that he would not take his son and he would be a bad father - not necessarily in that order). The golf will take up a small proportion of the trip.
AIBU to be pissed off?
