Need some advice

So recently me and my boyfriend have been going through some rough times in our relationship. He has been going through a lot of stress lately. We have been together for almost 5 years and he is worried that we don’t want the same thing in the future and our relationship won’t last. We both agreed to stick it out and give it our all, but I’m just scared I love him so much and he still loves me I just don’t wanna lose him. We have been through so much to give up now. Anyone got any advice on how to help?
