How Long Does A Rib Injury Take To Heal?

I box at a gym approx. 4 times a week. in the last 5 weeks I ve had 2 rib injuries, both on the left side. the 1st injury was from a low punch at the back which shifted my ribs and caused a spasm to my left kidney and the ribs caught the bottom lobe of my liver. The 2nd injury was a punch that caught the side of my left breast and squashed my 5th rib into my 4th! the ribs are still rubbing together and I m still sore from internal bruising.I m doing a couple of stretching exercises and making sure I take deep breaths! how long should I take off from training, and more specifically from sparring! my trainer seems very dismissive about recovery, but I am concerned that my rib may detach as this happened 20months ago with the same rib, and I am the only woman at the gym and so always spar with men! I love fighting, but am very small in comparison to my sparring opponents!
