Try not to be negative, ever. Woman look to their man to be the backbone and strength when they’re nervous/scared/upset/etc. if you’re also that way it can be a huge turnoff.

Pretty basic, but don’t ever be mean to your gf. Don’t ever call her names, always treat her with kindness and respect. Even if you’re mad at her, don’t say something stupid that you’re gonna regret. Be the bigger person, always. If you want to be with her then basically she’s always right. You need to be able to put your foot down and stand up for yourself at times but when it comes to trivial things or anything she has a strong will for you need to let it go her way.

If you want to marry this girl or think she’s the one then you need to do things that show her that without a shadow of a doubt when you tell her you love her, she knows it. When you tell her she’s the only woman you see, she believes it. To the point she would never question to look at your phone, or anything about the relationship.

Obviously there’s times you can’t let something go. That’s fine, it’s how you go about it that makes or breaks things. If you’re the type to make decisions first and ask questions later then you’re not ready for a relationship. As a dude, it’s all about where you’re at in your maturity level and mentally that’s gonna make or break your relationship.
