Is it my fault...?

Who's lying??? Lies in any relationship undermine the trust you need to make any relationship work.

"I don't wanna say what's on my mind" is another red flag, given that a healthy relationship needs communication to keep it alive. If you can't or won't communicate with each other, you might as well call it quits.

getting mad and fighting over "littlst things" it's a warning sign..means you're already heading to the what we call "a toxic relationship" and which means you should guys get some distance and try to solve it for good or better end it at this level before damaging eachother's feelings!! ⚠️⚠️

Then you should be glad to be rid of him. Don't go back. Don't look back. You have learned. Now move on. Plenty of years to find a loving, caring partner. Liars are intolerable.

Its good you broke up because he sounds abusive anyway .. unreasonable, immature, selfish and bad tempered

No it isn't your fault

Is he short,lean and pale? If yes then he is insecure. Not your problem

He needs to straighten out and get his own self in order

These boots were made for walkin…

No, most probably not your fault.

Sounds controlling.
