Love and family relationships necessarily involve a great deal of attachment. It's built-in to the process. Consider early infant development, for example -- those cute behaviors a wee one starts displaying, around month 4, are all intended to foster child-parent bonding.
Similar things could be said about courtship behavior -- i.e. "falling in love".
My advice then, for what it's worth, is to be realistic and acknowledge the nature of romantic relationships (and, if you get married, family life). Don't shortchange them -- if you're going to go down that road, put your heart into it and accept that it involves attachment and desire. Without these things, your relationship will not flourish. For now, you can focus on appropriate attachment and restraint rather than non-attachment and renunciation. When problems arise, as they inevitably will, dhamma can help.
So fall in love, and enjoy every minute of it! But avoid the extremes of obsession, jealousy, over-infatuation, putting someone on a pedestal, etc. Be an ethical person; keep the five precepts. Be considerate of the other person's needs and aware of your own delusions. Make commitments and honor them -- don't lead your lover down a blind alley. Don't be too "clingy". But be true.
Just my two cents.
