While it may not be a deal-breaker depending on who you meet and chemistry etc., the difficulty is not just a "liturgical preference" in my opinion, it is an entire culture, an entire way of life. Traditional Catholics aren't just different liturgically, we are different spiritually, culturally, and logistically. We look at things differently, we come to different solutions and propose ideas that most (forgive the term) novus ordo Catholics wouldn't dream of embracing. Translate that into relationships and you have in my opinion a chasm of sorts. Sure, the Sacraments are still the Sacraments and the Church is still the Church, but in my short time I have found that the differences unfortunately outweigh the similarities.
I would definitely aim towards finding someone of the same traditional perspective as you, but be prudent. I hate to give you that advice as the theology manuals say prudence is a "vicious circle", but that is the best we can hope for in this life. The purest form of love exists only in heaven, where there won't be any "liturgical preferences" I can assure you...
