Don't want almost 3 years wasted😔

My boyfriend and I have been together 2 years and 10 months...I haven't been myself lately and I think it's putting a strain on our relationship. We fight constantly about stupid things(they aren't big fights just bickering) and I can tell it's taking a toll on him. I love him more than anything and I want to fix this because I want to spend the rest of my life with him. I just feel like he's done trying with me and it makes me so sad😔This isn't so much as me wanting advice but more of me ranting...but if you have any ways that we can get over this or if you had a similar experience in your relationship please comment below.
