It doesn’t matter if you label it cheating or something else, the fact is his behavior is a breach of trust. From your own words, you both have insecurity issues that need to be worked out. You can’t fix his and he can’t fix yours, it’s a task you each have to complete for yourselves. My suggestion would be to take some time off from romantic relationships period and focus on yourself and working on your insecurity, otherwise you only continue to attract other insecure people into your life.

Best of luck!
