If you're not careful to keep things cool and casual between you, issues of jealousy, emotional manipulation, possessiveness and control could become major problems in this relationship. You provoke an intense response in your partner, which feels amazing at first. Their sexual attraction to you could be overwhelming, and they feel transformed by your intimate experiences together, as if they've finally found The One.
Sooner or later -- and probably sooner -- you begin to affect each other's moods too much; when one of you is down, you both feel out of sorts. If your partner needs some alone time, for whatever reason, you feel intensely insecure and abandoned, and you respond by trying to keep them with you by any emotional means necessary -- manipulative or passive-aggressive behavior are definitely possible. If I can just control my lover into sticking around, you think, and meeting all my needs whenever I want them to, I'll feel so much better! This is rarely true, though. Dominating another person never brings true satisfaction for either partner. Your individual needs for connection and love could keep you locked into this pattern for quite some time, unless you can find a way to communicate about all these big, overwhelming needs -- and figure out how to meet your own needs so you can come to each other free and clear of emotional baggage.
