Everyone pictures themselves in a very happy and healthy relationship. But you need to keep your eye open to observe when your relationship is taking a turn for the worse.
It is good to act as a support to the other partner, but completely denying him/her of his right to make a decision is not love. Yes, when you are in a relationship, you tend to feel a little bit of jealousy but not letting your partner even have friends of opposite gender is not a healthy sign.
Yes you should keep your eye open to whatever is happening in your partners life, but please learn to trust also.
SO, please, guys and girls, either talk to your partner about his/her behaviour or leave the relationship immediately but do not stay and suffer in the name of the love.
NOTE: DO NOT COMPROMISE WITH YOUR SELF RESPECT
LOVE WILL PULL YOU UP WITH ITSELF AND NOT PUSH YOU DOWN.
