I’m (M30) am not coping as well as my girlfriend (f28) and I’m worried she’s going to perceive me differently

We are a new relationship. 3 months in. Now 2 months apart.

We have come on far in a short amount of time, said we love each other, I’ve met her family etc. made plans for when I’m back.

It’s only been one week. And I’ve had days where I’m flat and sad and she will be able to tell on the phone. I tell her I miss her and I feel like I’m

Missing out on things in her life… events with family and friends. but the immediately start to judge myself because I feel like I should be solid and stable for her. If I’m ok, it will make her feel better too.

I’m worried now she’s going to think I can handle it, she needs to look after me, like I’m an uncertain or tough time I’m the one the cracks….
