What does it mean for my ex-boyfriend to text me once or twice every few months like this?

When you are free, you can respond to him with contempt, but you must think about the result: find a balance between your previous injuries and losses; Let him sit up and take notice, let him regret losing it and never get it again; Save yourself, the principle of saving yourself, don't be hurt by him, and don't think that he will turn back, because when you fall again, he will hurt you again, without feelings, remember!
