How do you guys handle this?

CH advises against any form of mate guarding. I tend to agree as I know my self worth and I'm good a dating girls and adding fun to anyone life.

This is my first serious relationship, others have just been friends with benefits and short term relationships.

My friends, they always tend to get jealous and it seems to form a big argument. I've heard females talk negatively about the boyfriends of there friends who mate guard.

My plan was to go into work all day, as my manager has offered my a lot of money to help test a new system. And he has asked me and some others personally. So I will be too busy

However.... If I do nothing, will my GF think that I don't care about her?

She just told me, she is going drinks with her team at work. I just said yeah okay have fun.
