Men are mostly challenged when it comes to relationships as they are much offended by many things and they make many mistakes. Some of them are;
1. The ambiguously or conveniently undefined relationship that only benefit him. It doesn’t even matter if the two of you would make a shitty couple.
It starts to gnaw at one of you that s/he is fine living in a world without boundaries or expectations. But when one of you is not cool with the situation anymore, then neither of you can pretend the relationship is working anymore.
2. The dirty little secret in your bookmark. You like porn. No shame in that. In a healthy relationship, there’s enough room for sex, intimacy and fantasy. Besides, sometimes watching porn helps you take care of your sexual needs without projecting them on to your partner.
3. Conflating familiarity with ennui and attraction with compatibility. You walk past an attractive girl in the street who twinkles her eyes at you.
Or one of your classmates (or coworkers) gives you flirty eyes when you talk with him. It makes you feel young (again). It makes you feel sexy. Eventually, you fantasize about that person just a tiny bit.
4. Settling for a shitty relationship because you're too lazy to find a better one. At first, things are pleasant. But then you stop going on dates with your partner.
Or the two of you sublimate all of your love and romance into your jobs, raising your kids, your dogs, anything besides actually working on your relationship. You don’t have real conversations anymore. You barely speak at dinner, and when you do, it’s about the food.
