Echoes of a shared past life as bitter enemies will still be felt when you get involved romantically in this life, making your connection both powerful, compelling and quite difficult. Your urge will be to control your partner at all costs, by any means necessary -- but once again, just as you did so long ago, you'll find that you have a worthy opponent. They will resist your displays of domination with strength and energy of their own, and intense power plays will result.
Let's hope you're both more emotionally stable now than you may have been in that previous lifetime, because the potential for conflict is great here. You can transform yourselves and your karmic connection for the better if you can keep your own feelings and behavior under control. Rather than simply following your instincts, which will tell you to use emotionally manipulative tactics like guilt, possessiveness, anger and jealousy to control your lover, you'll have to use your head and remind yourself to respect their autonomy. Talk out your feelings rather than acting on them. Be patient and fair with your sweetie, and gently encourage them to do the same. Above all, remind yourself that you're lovers now, not adversaries, and you should treat each other accordingly.Please remember, however, that if this or any relationship becomes emotionally or physically abusive, staying in it and trying to work out the troubled karma will not be a positive experience for anyone involved. Your first priority should always be to keep yourself safe. While this connection holds great possibility for personal transformation, it also holds the potential for destructiveness. Sometimes, the best way to resolve difficult karmic ties is to let the relationship go and move on toward something more fulfilling.
