Can TTC ruin a friendship ?

So I have a really good friend whom I love with all my heart and would do anything for her and her son. Recently she cheated on her husband for like the 3rd time and bad mouthed him so bad to everyone we know she kept talking about how she was going to leave and so on and so on. My husband and I have been trying to conceive and have had no luck all of last year and when she announced she was pregnant I was a bit heartbroken, but happy for her. She explained her husband and her had a goodbye sex before their divorce went through and somehow got pregnant. She had the baby and told me in secret she thought she could be pregnant again and they decided to stay together. I instantly felt jealous and angry how could someone who didn’t even want it get pregnant so fast ? I will always be happy for her and her beautiful children, but I can’t feel so sad why not me ??? Now I have a hard time being around her because of all the baby stuff.
