Unfortunately, the two of you together might spend more time blindly working out old patterns from past relationships than creating new ones of your own. You don't mean to treat this person as if they're an old story you've already heard, of course, but something instinctive within you just responds to them this way, and you find yourselves locked in a difficult relationship without even meaning to, or knowing how it happened. This aspect is too intense for a relationship to last; you tax each other without meaning or wanting to.
If you've ever had tendencies toward jealousy or possessiveness, or rash behavior in the thick of passion, this relationship only increases that tendency But becoming a more moderate, mature human being should be your goal. Don't put this person through that kind of trouble. Instead, turn your focus toward the future, toward bettering yourself and finding new, better ways to relate within a love affair. Ask yourself what you need to do to have a positive, forward-focused experience in love, and then make it happen.
