How to get a girlfriend?

Tough question brother. First of all you need to work on yourself. Maybe go to the gym or do skincare. Look on Pinterest and find a clothing style that suits you. Then work on conversing. Go on VRChat and learn how to talk with people properly and learn about general smalltalk topics. If all that’s done, start trying to talk to girls. No need to expect to be successful - just gain experience and gain confidence.
Someday it’ll work! Good luck.
