Should I keep giving him the benefit of the doubt?

I’m so over having a boyfriend or maybe I’m just over him being my boyfriend. A couple of weeks ago me and him had a disagreement over something I knew he was lying about and I was so ready to walk away then my mom pass away unexpectedly and at that time I was vulnerable I just needed a shoulder to cry on I just felt so lost and empty I still do actually but anyway I had my ups and downs with him mainly downs. I won’t be okay for awhile but I’m still trying to do the best I can and go on with life without my mom. So his birthday is next week and I order him stuff that he asked for he got 3 pairs of shoes two pairs of shorts and a chain that was 200 dollars and I was going to give him 300 dollars In cash to get whatever else he wanted because he kept sending me things he wanted through text. He sent me a 1,200 motorcycle I said no. And he kept saying he wanted to take off for his birthday I said you need to make sure you’re getting paid for your days off because he would have had to work on his birthday but he said he didn’t want to I said cool but you still need to get paid and he got irritated because he didn’t know how to check and they told him everything is on his work app on his phone and he never wants to show me his phone when I’m trying to help him he will say I’ll figure it out. And the reason why I said to him he need to make sure he’s getting paid because after his birthday rent needs to be paid and if he doesn’t get paid I will have to pay rent and whatever else myself like I was doing before. He’s so worried about taking off but don’t care if he’s getting paid or not but don’t know what he wants to do on his birthday.He said he want to get a hotel again away from here which was a couple of hundreds I paid for last year and I wasn’t doing it this year I wasn’t in the mood I just wanted his birthday to be over so I can grieve in peace and not spend anymore money. I just thought how funny it is how he wants to do this and that on his birthday and want me to get all this stuff for his birthday but when It comes to mine he’s only spending maybe 200 dollars or less. And yes this is my own fault but this is how I am I will give you the shirt off my back I’m so giving but it always bites me in the ass in the end. He brought me a pair of shoes for my birthday and took me out to eat last year he said he was broke and he was sorry he couldn’t do more but this is every year since I met him in 2018. He barley wants to work the 4 days they give him. So yesterday he wanted me to get him a ride home saying he was tired I said okay then he texting me angry saying he just quit because he cursed the manager out. I didn’t even reply this is his 3 rd job since we got this apartment that he either got fired from or quit and now all the bills are on me AGAIN. I told him it’s crazy how you’re so easy to quit a job when you don’t have a back up plan no money saved but all the bills will fall on me again and you could careless he said how? I just quit today I said okay do you have a interview tomorrow he said no I said okay then. I’m tired of giving him the benefit of the doubt.
