Ex left me due to my insecurities. He fuelled them by being dismissive and not reassuring. We shared so much but there were problems we didn't learn to communicate about. Is a 2nd chance possible?

I can hear you are reflecting deeply on this and want to make sure you make the right decision. Healthy relationships are usually ones where both partners offer eachother open and honest communication and immense respect. Only you would know for certain if you wish to give him a second chance. It might be a good idea to decide how you wish to communicate with him, what you need from him and this relationship and ensure you are both on the same page. Remember that it takes both people to make a relationship work. I wish you the best of luck.

Your ex left because you had insecurities that he had no idea how to handel and ended up making it worse. You guys had a connection although you guys had problems which you guys couldn't communicate well on. Do you think a second chance is possible ?Think about it if you did that to him. Would he give you a second chance? Every one has insecurities and they should be turned into power not be weakend more. With all due respect do YOU think he desreves a second chance. There are many fish in the sea if you go for a shark it's going to end up eating you no matter how many times it says it won't. You deserve better, if you think he is forgivable than go ahead fogive him because only you know best in this situation.
