It’s tough for someone to nail down to source of feeling not OK, but they unconsciously latch onto things that will get rid of this feeling, usually through reassurance or trying to make situations come about that they feel will make them happy and finally grant them relief. This inevitably impacts your vibe, you become a parasite of sorts and everyone you come into contact with is simply a means to an end.
Be calm and confident in yourself and what you think you can contribute to her life. In the time you've taken to improve yourself, hopefully you will have evidence of that change. If the cause of your breakup was that you did not have enough time for her, show that you've altered your work schedule and made time to volunteer or pick up that sailing hobby you've always dreamed about. That will show you're willing to make time for things that matter to you. See where I'm going with this?
Take responsibility for your mistakes. Avoid making excuses, blaming your partner, or dismissing the affair as “a one-time thing.” In order to ask for forgiveness and begin moving on you need to take ownership of your infidelity. By taking a good, hard look at yourself you can eventually realize what made you decide to cheat and find ways to avoid making the same mistake.
Two months ago I met a man. We were so attracted to each other that it all happened so fast, on the first date. He warned me that he didn’t want a relationship… I did my best to listen to his feelings, show understanding and get some intimacy and we eventually got close and started meeting every week. I was sleeping over at his house, we were having good time, having sex, doing normal things like cooking and spending the whole weekend together. I knew he had a very problematic past – a father who never married his mother or took any responsibility, a brother from another mother who caused him problems, personal problems with drugs in the past and two broken relationships with 1) bulimic anorexic girl and 2) a girl who cheated on him 10 months ago. I was so good to listen, give him the peace he needed and be very patient with him.
Hopefully, these tips give you something to work with, and you will find something that can help you approach your relationship problems in a different way. You don't have to be Freud, you don't have to do it all at once; instead, see which of these ideas catch your attention. Then pick a situation, a pattern, a problem, and map out a different approach, a concrete behavior that you can put into place. Start small. Focus on you. One change will lead to another.
Make sure you want your ex boyfriend back for the right reasons. Are you really still in love with him? If so, it might be worth trying to get him back, by showing him you still care and that you believe things will be better this time. Sometimes breaking up provides time for both people to realize that, more than anything, they just want to be together again. However, if you have any other reason for wanting your ex back, reexamine whether it's a good idea to try to rekindle the relationship.
If a man is honest and tells you he does not want a relationship, then as a woman you should honor his truth in telling you this and take a moment to reflect and understand that you may need to pull away. Not to mention, if he also gives you the popular one-liner by saying, “I’m just seeing where things go,” proceed with caution. This is not a committed answer, so why would he want to commit to you? This is just an answer to lure you away from the truth in hopes to keep you around for what he is in search of pleasure and attention.
