Pregnant with friends who can’t conceive

So I am 6 months pregnant Sunday, but a very close friend of mine has been having issues conceiving. She’s just found out she will have to go down the <a href="https://glowing.com/glow-fertility-program">IVF</a> route, but has shown very little interest or support to me, almost like she resents me for being pregnant. How have people tackled this before? I feel angry she can’t be happy for me despite me totally sympathising it must be hard for her. Thoughts of how to cope?
