The one thing not mentioned is.........the "s" word.......i think you should just forget his offer as to me he wants only one thing and he knows that he will get it from you (no offence)! Maybe in Ireland he is not "wanted" that much - if you follow my meaning......respect yourself and decline him...
Thats my advice!!!
Also if you have broken up three times then doesn't that tell you something???
Girl is fragile sometimes, especially in entering a circumustance. though to travel in Ireland is not an
difficult things, you'd better think it clearly as many unexpexted ,unpredictable things may comes to you.
At that you will regret to go there.
anyhow all of this is only advise,
think twice before you leap.
Go for the trip but not as a gf or anything like that. It might be fun. As far as ireland being boring as someone else mentioned, I've been there and it depends on you. It's small and has different places to see. Dublin is the capitol and has quite a bit to do and there is lots of scenic beauty elsewhere.
