Newbie and long post.. sorry. Just back from 5 days abroad, new relationship (3months) all was perfect until I got a dodgy stomach last night. About 10pm said go down to the AI bar enjoy the last night (we had made friends (couples mostly).He said I will have a couple of drinks, get a kebab. Half an hour later he's sat at a table with 4 German girls (about mid 20yrs) drinking tequila, and whatever else. From the balcony I heard him comment on one girls boob size, being flirty, telling them all where he comes from. Then one girl said 'if it's not working, do something about it'. He saw me sat on the balcony and they all shouted for me to join them (in my pjs, dodgy tum and really angry/upset). He stayed with them another hour before staggering back to the room. It was an awkward flight back today and he thinks he's done nothing wrong.. any advice please?
