I know this is hard and I am so sorry that you are going through this. You have dated a man that is emotionally unavailable and is following the same pattern that he had in his life. You mentioned his father never married his mother so this is an issue that he has to overcome himself. This is his past playing into his life now. You have to make yourself less available to him and understand that you deserve more than this. I would encourage you to book a session with me or a male coach on my team so we can help you during this time. You can reach out to me on my contact page. If so please state you messaged me on my blog so I can remember. We are here if you need further guidance.
Texting your ex does pose a risk. The risk being that he rejects you or just doesn’t answer. You should always be prepared for that possibility and just be OK with it. If you won’t be able to handle things not turning out the way you want, then you aren’t ready to get back together with your ex in the first place and need to spend more time on your own working through things.
Your relationship with a special guy has come and gone, but now you want him back. It's not unheard of for a couple to get back together after they've taken time away from each other, so don't give up hope. Just be sure to put plenty of thought into the reasons you broke up before attempting to get back together, as this can help you make the relationship work the second time around.
Another frequent error is wanting to talk constantly about the past in your messages. You have to stop focusing on your nostalgia and on what you’ve experienced together. You ex needs something else. It’s of course tempting to send a little message saying, “I miss you,” “I love you,” or “My feelings for you are still strong.” Truth be told, during this stage these types of things can damage your odds of success so refrain from sending them.
