You’re not the same guy that first attracted her – When you first met, everything was new and exciting for both of you. But over time as you become more comfortable with each other, certain things become a bit stale. You need to remember what it was that she loved about your personality in the beginning and be “that” guy again.
You suck in bed – Bro, you seriously need to work on your bedroom skills. Learn how to make her orgasm, read up on some foreplay tips and become the bedroom ninja that she’s looking for. If you aren’t satisfying her, then she’ll get bored REALLY fast.
She needs more excitement – If you’re sitting at home every night with her, this will get extremely boring. You need to plan some date ideas that will surprise her, that you’ll both enjoy. This will ensure that she doesn’t get bored and actually looks forward to seeing you.
You’re far too insecure – Everyone has some insecurities, but if those insecurities are getting you down and you actually have more than her, this can be a huge turnoff for her. Women like strong, confident and secure men… you need to be that man.
You’re too negative – Negativity is a drain on energy for both you and her, if you’re always negative around her she will anchor these bad feelings and begin to dislike you. So stop being such a douche and be more positive bro.
She’s feeling undervalued – Girls need attention from their man, if they feel as though you’re not giving them enough attention they will look for it elsewhere. Now you don’t need to smother her, but you do need to keep things spontaneous so that she can see that you care.
To get you back for cheating on her – If you cheated on her before, then there’s a chance that she’s looking to get you back. Women can be spiteful, so this will always be a possibility.
