So, now that you know what changes you need to make physically lets talk about arguably the harder thing to improve, your mental state. One of the biggest assets about the no contact period is that it gives you time to calm down a bit from the mental tension that was your breakup. This section is going to be all about how to get through your breakup and heal emotionally. However, in order for that to happen you need to take a few actions first.
Apologize. Think deeply about anything you did or didn't do that somehow contributed to the downfall of the relationship, and clean the slate by giving your ex a proper apology. Take full responsibility for the offense, without blaming your ex, giving excuses, or expecting an apology (or even forgiveness) in return. It may very well be that your ex contributed to the situation, but you cannot apologize for someone else; you can only apologize for yourself. Leave him or her out of it and odds are the apology will be reciprocated.
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, ā€œIā€™m just seeing where things go,ā€ 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.
