why can't she just stop being so obsessed with my man?

i ask a question last week about my bf lied and got another woman pregnant... it turns out that that woman called me and lied to me because she wants me to leave my bf so the she could have him, my bf told me that this woman is lying just for me to move out, it's like she is obsessed, she texted me all day to tell me that my bf comes to her house, kneeled before her and beg her not to leave him, me and my bf got back together and things are going ok, i decided to forgive him because i love him, he is my baby-daddy, we've been together for 10 years and he told me the truth, i know he cheated on me with her and he don't deserve my time but anyways, yesterday that bi*ch text me and tell me that she abort the baby and that now i can be in peace don't think about it and hope that i'll be happy with my bf, i told her all that was on my mine and told her to stop bothering me, when i got home i showed my bf all the text my bf said that she is a motherf*cking liar and that if the baby was really his why didn't he keep it as a proof, she is doing this on purpose, anyway only God knows the truth, but that woman is so sick but there is always something about this case that i need to find out it's like i can't drop it because i want to know if my bf really told me the whole truth. what do you think?
