pregnancy

one of my old close best friends was pregnant didn't know who the dad was (she was engaged) but cheated on her fiance well she found our she was pregnant and immediately jumped to the conclusion that she wanted an abortion do I have the right to be angry at her? I've had 3 miscarriages and she never once believed me. so once I found out I was jealous and angry. she ended up keeping him but for some reason I can't help but be angry with her for even considering abortion.
