How to increase my bench? I'm stuck

I'm 5'8, at 155lbs my starting weight 7 months ago was 135lbs.

When I started benching I was doing 90lbs x5/10 or something I think.

Right now my bench is at 135 x4-5. Although a week ago I managed to do 155 x4 with a spotter. Otherwise my max is 155 x1. And it's been stuck at this level for about 1 month ish, maybe 2. I go to the gym 6 times a week. I bench rvery chest day etc. Aswell as squatting every leg day.

What bothers me is I've gone from 155lbs x3 to a 175 x3 and a 190 max squat during this time while my bench hasen't progressed. So I'm still gaining.

My form is good according to everyone I've asked. I've been eating around 2500 to 3000. Although I've slacked somedays, and haven't gone up to 3000 due to not counting the calories I guess.

I just want some tips on what I could do to really get my bench press going again? Anything is appreciated really.

TL;DR: My bench has been stuck at 135 x4-5 for 1/2 months, even though I have proper form
