Allowing the sex to dwindle
Nobody has the right to force you into doing something you don’t want but if you’re someone who has always enjoyed sex, you should be taking out time to enjoy it with your current partner. If you just suddenly decide to stop sleeping with your partner or if you randomly go days and weeks without doing it, it’s very likely that your woman will find someone else to fulfill her sexual needs.
Trying to change your girl
You can’t force someone into becoming the version of their self that you like better. It’s just not how it works. And if you keep trying to change things about them like the way they dress up, the music they listen to, the past times they choose to enjoy, they’ll end up resenting you for it.
If you can’t accept a person as exactly who they are, the problem lies with you and not them.
Not knowing what you want in life
The biggest deal breaker in a relationship is never being sure of what you want. You feel like the girl you just met is the girl of your dreams and you make her feel that way too. But a few months pass by and you realize you were probably wrong. Don’t hurry into things. Don’t make someone else suffer because of your own indecisiveness. Take time to think about what it is you truly desire and move forward with that.
