i think u should. or ask ur bf to go with u. either way, i wouldn't pass up the opportunity if i were u. travel within europe is a lot easier/cheaper than going all the way back again some other time, ykwim?

and if u do go alone, u can always meet other travelers (esp if u stay at like hostels or backpacker hangouts) and ime there are always cool ppl willing to do stuff together so no one has to be alone. :3
