Stole money

I am 48 years old and in a telation with a man my age ,we r engaged but since i knew him i felt that there is something missing in the relation and i wasn't sure that i love him and kept postponing marriage.he is so kind with me and generous in money issues .but sometimes he gets out of money and i lend him and he return it. days ago he was at my house and he took money from my bag without telling me. I discovered aftet he left and called him and told him u took money from my wallet in my bag

First he said no and how come u accuse me of such a thing and i told him u r a thief and i ended the relation
Then second day he sent me a message addmiting that he took it because he wanted to gey my fruits when he went out to get cigarrets and he exceeded his atm limit and didnt have money and didnt find fruit around but couldnt put the money back in my bag
Then third day he sent that he took the money as a test for my trust to him because i always hesitste about our relation and he wantedto know if i trust him ir not and that if i find missing money i wont ever think that he is the one who took it. And i failed in the test and he is so sad that i dont trust him. I dont believe these excuses and i told him no way back together. He is going crazy sending messages that i am the love of his life and he is not a thief it was a test. Now i dont know y i am sad. Am i right in my deciision to keave him forever or he might be not lying and he took the money for that stupid reason
Note :i suspected once before that he took the same amout of money from my bag but i convinced my self that i counted my money wrong. Plz help me
