Quoting Baby Brooklyn Due October:" Hhaha okay. Well, I'll try to explain. She is sick in her own mind. Im not being mean, I love her to ... [snip!] ... but im here to care for her. But if i had a baby too I would lose it. Expeccially just trying to keep it from not getting sick!"
Ok, well this is sounding More & more like she's either Abusing you guys, OR she Needs to hit Rock Bottom & you guys Move out.
& Then report the situation to Social Services. Or report to them so they can help you Move out & her.
You're going to be a Mother soon, & it's called "Tough Love".
You will more than likely end up SERIOUSLY resenting your MIL as you Grieve for the Baby you give up(& it will be a life long thing, especially since you DO want your baby, but your Temporary situation right now is as it is). & A Good Adoption Agency will probably tell you the same, or their Counselors will as well. & if you Do plan on Giving your Baby up, You really really need to see Adoption Counselors who are Pro Birth-Mother, not the kind that want you to just give the Baby up, so that the Agency can make $$ off Giving Your baby to someone else.
