If you love your current boyfriend then don't do it, 99 times out of hundred it will simply cause problems with your current relationship. Maybe not now but in the future.
A brit does not just fly over to phill for dinner (well the average brit doesn't anyway). What else is doing over there, tourism, meeting other friends?
Best to politely decline.
If you still have feelings for the exbf, you need to decide which man should be your boyfriend.
