where is your sticking point?
And if you aren't running a set program right now get on some straightforward linear periodization, it's simple, easy to follow and you can usually pick most of the assistance work, try the Coan bench calculator here: http://www.joeskopec.com/edcoanbench.html
That gives you your second pressing day pretty much totally up to you and additional heavy tricep and incline work on your heavy bench day
I would suggest military on your alternate pressing day and whatever your weak point is, but to know what you're weak point or points are post a video or give an explanation on your sticking point if you have a consistent one.
the fact that you gained a bunch of weight and your bench didnt go up at all suggests to me some kind of mental block as well, honestly it's really strange that your bench stayed at 245 when you gained that much weight, good luck man.
