Break up

My daughters dad broke up with me , last year I gave him money to purchase a car so our 1 year old wouldn’t be in the cold during winter. I have him the money and he went to the lot to pick it up. I gave him 7000 for a car . I’ve been paying the insurance on the car because I make more money . The car got totaled snd he got back a value of 12000 for the car. We had split , but he told me he was getting a new car so I didn’t worry I was tired of taking Uber’s with our daughter . We got back together and I asked him where was the money for the car and he said he spent it . I said on what . I have so many bills , medical so backed up . I know he didn’t buy anything for me or our daughter during our time apart not even groceries. So when he told me he spent it I was upset and gave him a piece of my mind and told him that he is selfish because he is . Why man has 12000 dollars and doesn’t purchase a new car but didn’t even say he’res the 7000 you gave me towards the car . So he broke up with me for mentioning that to him . Then today we argued and he mentioned how it would of been more fun to make a baby with someone who can have sex . We did ivf for our daughter. I don’t even want to speak to him for a man who I did everything and so much for to use my infertility against me says so much.
