Rough going Thomas, sorry it didn't work out for you in Spain.
As for me, I've been dating non-Irish women for years. I've interspersed a few Irish ladies in there for quick encounters and a bit of fun, but I haven't had a proper Irish girlfriend in over 8 years at this point. But since then (not including punting), I've dated Polish, Italian, Finnish, Tunisian, German, Greek, Spanish and Austrian. I guess the world has such a great variety of ladies, I'd love to sample them all!
Real integration will take time of course, but I don't think it's impossible, and people will open their minds to new people eventually.
