Your partner may also feel jealous.
Feelings of jealousy are normal. If the jealousy becomes very strong, it can become a problem for you or your partner. Neither you nor your partner have to be jealous to prove that you love each other.
If you or your partner react in a jealous way, try to understand what causes the jealousy. Talk with your partner about the effect of the jealousy on both of you and about your expectations and limits.
