I'm nervous with my gf and new coworker
Why ae you nervous?
Yes I'm sure. I hate how my gf cries when we fight and my coworkers is so much better than me and it makes me feel insecure and bad at my job.
It is hard to trust when your self-confidence is low and you are scared that you are not good enough. But it will harm the relationship if you start doubting your partner.
I guess, but I'm still nervous with my new coworker.
You should respect your partner and feel secure in your relationship. If work is stressing you out you can talk to a therapist. Would you be ok with that?
