Does jealously ruin a relationship?

I never want to envy anybody, the success of other people with me okay, but if they are not a regular love, if my boyfriedn with the other girls enjoy good relations, i would be very jealous.

I dont really know how to put this so it makes sense but jealousy is a normal thing, it is when it becomes mis-trust that it becomes a problem, I get jealous sometimes if I see my partner talking to another girl and getting along with them well, but I know that he would never cheat on me so that is as far as it goes, but when someone gets jealous and then starts carrying on that their partner is going to cheat on them that is when it will become a problem as they obviously dont trust their partner. If someone is making you jealous on purpose that is a bit mean!

Yeah jeolousy can ruin one's relationship though its a sign of love. You must control yourself and hide your feeling if someone wants to make you jealous otherwise the person will succeed what he/she is upto.

Of course. And he or she will do something crazy!
