Hi S the F, I just happened to read your question. I really don't thing that there is there should be or is emotional cheating.

I don't know how old you are, but being human means desiring knowledge and wanting input from others.

So, you are not doing anything wrong by letting yourself meet and talk to other people. What you need to think about is what your intentions are.
If you are seeing someone, than you need to let them know that you like to meet new people and learn new things. If your boyfriend is restricting you from reaching out and growing, and if he is restricting you, this is not a good sign. Your boyfriend is showing you that he is not confident enough in himself and that he wishes to control your world.

Should your relationship with him proceed with him controling you, it will not be a healthy relationship. So you need to help him understand that you are not going to be controled by anyone.

Healthy relationships are about allowing your partner to grow and be themselves. A healthy relationship never involves control over another individual.

Your statement, "I am a terrible person" is an expression of either you do not wish to be contolled and you have allowed yourself to be controlled and you want to break free. STOP, think about what YOU want. The only way guilt should be allowed into the picture is if you are encouraging your boyfriend to feel that you are only interested in having a relationship with him, when you actually are just clutching him and shopping at the same time.

It is normal when we are in a relationship to keep viewing the outside world and grow and then re-evaluate what we have and if it is what we really want. If you are young, and you don't really know what you want,
this is normal. Honesty is always the best policy.
