Weight loss plateau

Hello guys, I started my weight loss journey on last year and have made good progress for the last 7 months, but seems like I have hit a plateau.

I started jan 1 at 260 lbs and today weighed in at 215 lbs. The breakdown is as follows: 1st Jan - 260 lb 1st Feb - 255 lb 1st March - 249 lb 1st April - 238 lb 1st May - 230 lb 1st June - 222 lb 1st July - 217 lb

As you can see the month of June I couldn't keep up my approx monthly 7-8 lbs of weight loss, which is fine but July has gone even worse. I feel like I'm eating very less and not getting satiated.

Currently in eating 1800 calories and also running 3 miles everyday. I built this up slowly. I was running 1 mile everyday in January and slowly built up to 3 miles.

Do I need to up my calories as I feel the unsatisfied with my result for the past 2 months. Given it's my fault for binging alot on weekends and parties. But feels like 1800 is very low for me to sustain. Also I want to increase my miles to 5 miles everyday eventually.

My end goal would be weighing around 170 lbs.
