Boyfriend& break

We’ve been together for two months and lost a lot of ppl when we got together and it seems stupid but I love him. He saw his ex at a football game today and got mc donalds. He’s so toxic he’s always high and doesn’t care about anyone but I went through the exact same thing the year before and I don’t think he understands we need eachother and I know he loves me but he needs a break and wants to get back but isn’t sure when and I will wait but how do I make a guy with no cares want to have me
