My Boyfriend had a baby...

So today my bf moms call n said his ex gf had his baby. As the gf of 6 months which feels like 6 years i dont know how i feel. I had to terminate a pregnancy back in april & seeing the baby made me wish i was pregnant again so i can experience it till the end. Ive been ttc since then thats why i downloaded this app. Nothing yet just giving it time . Anyway his family is okay with me seeing him time to time but im unsure of how much i should get involved because of how his baby mother will feel about it. Anyone with advice?
