Look man I had girls my whole life since my teens years, always had luck with women and I had the love of my life during 3.2 years, we were to marry and start life when she changed her mind and we ended our relationship.
I decided to stay single for a while & have been since April, what I can tell to you is that being single is so much better.
Relationships aren't worth it because love is temporary these days, with today technology you can meet so many new people that attach yourself to someone isn't worth it anymore, people might disagree but that's the hard truth, many of my friends have betrayed their girlfriends because they were afraid to end the relationship even though they didn't love them anymore, they were afraid because they were comfortable with that person, not because they loved them.
Look guys, have Sex, date girls but don't put yourself into a relationship, it's cool at 1st but then the problems start coming your way & you'll remember this post.
