Buddhism does not contradict romantic love; Buddhism contradicts romantic obsession. Granting that this is a terribly difficult discrimination for most people to make — confusing love with obsession is the typical forof almost everyone in almost every place — it's still an important discrimination to make.
When you go into meditation you should strive to free yourself of attachments, even attachments such as love. When you come out of meditation and head back into normal life, you should carry that meditative equanimity with you and allow it to apply itself to your normal interactions and relationships. This will help you to separate love from obsession; to rid yourself of jealousy and possessiveness while deepening your affection. There is no contradiction between loving one person particularly and loving everyone generally. That is merely an obstacle that your mind imposes because it is confused and frightened, so don't become attached to that fear and confusion.
Yes, loving anyone (specifically or generally) is a condition of risk, because love (like everything) is subject to change. It's worth considering: Does a buddha suffer when s'he sees people flounder and fail on the path and cause themselves misery? We often talk about the compassion of a buddha, but compassion is inherently a shared suffering, and a love that overcomes it. A buddha must have compassion for h'erself as much as anyone else.
Maybe it's time for you to cast off all worldly relationships and join a monastic order; that would be fine, if you are willing to commit to it. But if you are not going to cast off all worldly relationships, then it is on you to bring your practice into your worldly relationships, not use it as a shield to deny them.
