Girlfriend screwing me up

Here we go in short my girlfriend has 4 children one of which is mine the other 3 she had with an italian guy before i meet her. 2 years ago she said that the kids wanted to see there dad and that he would send tickets. Anyway they had there holiday but my girlfriend told me that her x had put her in a bad position and they had sex. i believed her sa although i was really hurt i let it go. Anyway 2 years on she says the kids want to see ..... blar blar and that shes going again. she promises me that this time nothing will happen. i can't make sense of this, and its tearing us apart. i know shes going for the kids but this can't be right. Am i being unreasonable or is she taking thepiss!!

I read your post, and to me, the answer is simple. You are going to go with her, because you are her boyfriend. If nothing is going to happen when she is over there visiting, then what could be the issue with this arrangement. I guess her ex could say there us no space fir you to stay at his place, in which case, find accommodation for you, your girlfriend and the kids - you can see 'the ex' during the day time - it doesn't matter if you have to stay somewhere else for a few hours to get some sleep. If she doesn't agree to you going over with her, then I dont think she is serious about moving on with your relationship. Hope this option is worth considering / viable financially.

Thanks for you input Andy. I have put this forward, in short she says the kids want her to stay with them because they don't all feel comfortable with there dad, especially his 10 year old daughter who barely knows him. i Have suggested i come along but she feels that this will cause her to feel akward. Ontop of that the location is a tiny little village of which his family basically own, all the restaurants, beach bar and half the shops. She thinks if i go it will create an us and them situation which will ruine the holiday, and probably end in an ugly situation. thing is i feel shes discounted how i feel about whole situation she says she understands, but bottom line her and the kids are going. to be honest im thinking of just breaking up, i think she shouldn't of put me in a lose lose situation. ontop of that i have a big job starting around that time. i know her x is using the kids to get to her and its driving me crazy!
