Should I be bearing it or not ?

So here's the thing ....that things are actually not in good terms in my current relationship.....what happened was we had planned a date which was pending from a long time and in the end ... actually specially to highlight the fact that he ditched me and went home ......okay what could I just say in this....but after coming we had a tremendous fight and I wanted a breakup but he somehow manipulated me into meeting him ....and i eventually went.....I paid the bill of all our food....i had a talk about breaking up.... Cause it was too much....these arguements were going on from a long time and I did not want to continue this toxic relationship....but again he convinced me that he will change and all that stuff he would regularly come and meet me....cause we are in the same college and he never does an effort to meet me...isn't it ridiculous......meanwhile my friends weren't convinced of my decision to give him another chance....and warned me about it.....and what happened he again did not come to meet me the very next day of our fight.....and infact he did not even talk to me in the call....he just called me and said I am going to sleep ....and just nothing.....I just feel so joker kind of right now....it's so bad of him .... am I right in thinking that I should have a break up ....matter is I am an introvert and I fear i would be alone if he would not be there..... because of this I am bearing with such toxic behaviour.....what should I do
