There's nothing wrong with being angry and jealous! It works better in relationships to let someone know when you're angry and jealous rather than just going off on them with no warning but if one does push someone away, an apology and explanation of what one felt and why goes a long way to help the other person understand and come back close again.

I don't believe people mind that we're angry, jealous, etc. it's the unexpectedness and lack of explanation that frightens others off. The more one practices experiencing and naming one's emotions as they happen and keeping others informed as to what one is "like" the easier it is for others to stay around.

A lot of borderline behavior others don't care for is the suddenness and lack of explanation ever. Working with one's self to notice it too, when it happens, and link cause to effect and keep others informed makes one understandable as others experience the same feelings, just not so "out of the blue" where no one else has a clue what's happening. The trick is to try to keep in contact with the other while one gets in contact with one's self and works it all out, "out loud" with words rather than through actions/acting out the feelings with no explanation.
