This may be the best advice. Be happy. Don’t put on a façade. Be happy because you deserve happiness. Have you always wanted to travel to Paris? Book that flight! Have you desired a new career? Go back to school. Want to learn a new talent? Sign up for that painting class. Whatever it is that will make you a happier, healthier you, do it! If your ex sees you living out your dreams, he may miss you and come back. If he doesn’t, one day you will realize you don’t care. Guys really do like happy girls the most because they want to feel good when they're around you. If you're constantly full of drama when he’s around he’s going to start associating feeling bad with being around you and this is going to end things rather quickly. When you’re happy around him he’ll also be more inclined to reach out to you the next time he’s having a bad day.
I would just go ahead and assume that he is telling you the truth. If he is trying to work through some problems or he is trying to figure things out with an ex-girlfriend, it may take a bit. I am surprised that this has been going on for a year though. It seems like it would be fairly easy to figure just about anything out in an entire year. Are you sure that he is actually single? What exactly is he trying to work through right now? Have you guys talked about being exclusive yet?
Have you ever noticed that when you put all of your focus on someone it seems to push them away? That's why removing your focus from your ex will actually draw him closer to you! This is when meeting new friends will come in handy. If you really want your ex to miss you, you need to step outside of your comfort zone a bit. Of course it is important to keep a strong support system and keep the friends that you have made throughout the years, but expanding your social circle and making a few new friends can’t hurt either. By expanding your circle, it will fill up your social calendar with various events and outings to keep you busy and to keep your mind off of your ex.
Maybe your man is pulling away because he needs space. Most women don’t realize that they are a clinger due to which their men start spending less time with them. This problem is very common in young couples, but it could also happen in an old relationship. Men need space and they want to spend more time with their friends or in their man cave. The problem with many women is that they become too clingy or attached with their man. They want to know about every place their boyfriend goes to and every person their boyfriend hangs out or talks to. Clinginess kills any relationship faster than any other thing. To avoid being a clinger, try to keep yourself busy in activities outside of your relationship with your boyfriend. This will give you and him time to realize this that you both want to spend time together.
