Advice Needed What to do, if you overthink about relationship?

Ok, looks like you are holding information on us.
Whatever the reason you are doing this, it is ok.
Sometimes she is not that much of a, lets say, "huggy" person.
Sometimes she has to figure out some issues she has with herself.
I dated for a short time a girl who would not go third base.
After we broke up she told me she had a problem that made it impossible due to psychological trauma.

It is ok to care about making out, it is part of the relationship.
If you think you can't handle it, break up. It is not worth staying in a relationship you do not enjoy fully. In the end you are going to cheat on her or she is going to cheat on you, and it is because you couldn't be hoenst with each other.
You will find someone who you can tolerate. Yes tolerate because you will never find someone perfect, just someone you can live without issues and be happy about it.
