So lets get this right, do I breathe out when arms are stretch out in front(breaststroke) and in whilst pulling back?
Exactly.
As a beginner you will probably find that your glide phase is minimal and it'll be more of a Kick, G.., Pull.
The technique remains the same, blow out hard, but explosive like, think of blow-football, at the end of the Kick, G.. phase, open your mouth, well above the water line during the pull phase and the air will rush in.
If you watch competitive swimmers, their face is submerged during the kick phase and they may not breathe every stroke. You don't need to mimic that in your early learning.
A good buy is a swimming float, like this:

Don't be tempted to try a bit of Expanded Polystyrene, it's not the same and you'll make a mess with bits of it floating on the water.
A reasonable swimming float will last your whole swimming career and that of your kids. (And when you get really old they're excellent kneeling mats)
When using it, it's either between your legs, just above your knees (another trick to master, but not difficult, but ammusing when you see a classful of kids trying it, they're popping up like ping-pong balls) and concentrate on your arm technique, or use it in your hands (arms extended in front of you) and concentrate on your leg technique.
Either way you can also practise your breathing.
Obviously it's good for all strokes practise, except I've never tried it with side stroke!
Competitive swimmers use it in training so it won't look silly. Depending on how friendly the staff are at your local, they may let you borrow one.
Another good practise, either with the float or without; see how
few strokes you need to swim a width. You'll be developing technique and power in your stoke and it'll focus your mind on the glide.
Another point early in your breaststroke learning:
If you find that you're tending to use a screw kick, concentrate on keeping your shoulders square! Your hips will follow.
You'll realise what I mean by screwkick quite early.
Later in your swimming career you'll realise that the different strokes derive their power phase differently;
Breaststroke from the legs,
Crawl, backstroke and butterfly from the arms.
