I can't afford to buy a new oil furnace right now

My stupid boyfriend went to jail multiple weeks ago, plus he is still there, he still has 3 more weeks left on this sentence. He was the only man toiling at the time of his arrest, plus I had to get a job when he went to jail, and i found something hastily, which was genuinely great. I was toiling at a pizza joint delivering pies, soda, plus a variety of baked treats, and during the first few weeks, things were fine. It was Summer plus the tourists were abundant. Unfortunately, the pizza shop has been slow this week, plus the owner split my minutes almost entirely… Then last week, they finally fired me. They found out that my boyfriend was in jail plus they told me that was against their code of conduct policy. I thought I was doing a good job. I was toiling genuinely taxing plus I was even toiling overtime when advised. I am genuinely angry, because my stupid boyfriend got me into this entire mess. He was doing a lot of good things, before his sibling came back to town, as soon as his sibling was back in the picture, my boyfriend started staying out late plus missing work, now all of us are in a load of trouble, because the oil furnace needs to be upgraded, then my mom plus Mom will not pay for a new oil furnace, because my boyfriend is irresponsible. His parents will not pay for a new oil furnace because he is in jail. I don’t suppose what to do, because I have 3 kids plus no heat in the middle of November. The temperatures are only going to get colder, plus the oil furnace is done for good.
