I think bench press is so difficult, and, at least for me, the most difficult lift to get perfect form with. Keep at it, and keep varying the way you're lifting to make sure you're well rounded. Changing grip (for instance, one day wide grip, one day close grip) can help you break through plateaus. Trying different assistance work (dumbbell press, floor press, one arm press, pullovers, flies, etc) can be really helpful too. I've found (and heard the sentiment around) that incline bench doesn't do a TON to help out your flat press. If you feel nervous about the weight and don't have a spotter, drag a bench over and bench in the squat rack with the safetys right at your chest level to keep you from getting pinned too bad if you just can't push it up. Strong tricep accessory work is vital to a strong bench press, in my opinion.
Upper back pulling like face pulls are a good idea to mix in with your bench, as well, if you're interested in push/pull supersets
Don't worry, you're liftin big, keep at it and you'll get wherever you want to be!!
