Here are some signs that fears may be interfering with your relationship:

You avoid intimacy: If you are afraid of being intimate with another person, then you may avoid physical contact, emotional openness, and communication in general. This can lead to you and your partner being far apart and estranged.

You control your partner: If you are afraid of losing your partner, you can start to control his life. You can demand that he stay away from other people, spend more time with you, or do whatever you like. This can lead to your partner feeling limited and blocked in the relationship.

You are constantly looking for validation: If you are afraid of not being loved or desired enough, then you may constantly seek validation from your partner. You can demand that he tell you how much he loves you, give you a lot of compliments, etc. This can lead to your partner feeling tired of constant demands and lack of trust.

You often quarrel: If you are afraid that your partner is cheating or cheating on you, then you can often argue and create conflicts. This can cause your partner to get tired of the negative emotions and start avoiding you.

If you have noticed these signs in yourself, then it may be worth working on your fears and finding ways to deal with them so that they do not interfere with your relationship.
