Relationships are hard. I got out of one of 3 1/2 years and he totally screwed me over. This was back in January. I have been over him a long time before we broke up. He constantly contacts me and wants to get back together - sends me nude photos, etc.
You just have to be strong. You don't have to jump into another relationship, but go on dates - meet new people. Like everyone always says, "Plenty of fish in the sea." If you give yourself that opportunity to "let go," you would be able to do it.
Till this day, guys always tell me that I am "cold-hearted." I don't fall in love quickly and men that I sleep with is just that, men I sleep with. They think that I should be in love in order to have sex. I'm like sex is sex, love is love. I'm not looking for a relationship, but when they come to visit, I treat them like Kings. I can't say the same when we're just texting, talking on the phone, etc.
If you would like to read self-help articles, I highly recommend the site below - I suggest this site to all my friends getting over breakups and heartbreaks. And to this day, it has helped them a great deal.
Hopefully, the articles can benefit you as well.
Be strong. Be happy. Be confident.
