MsSuzie - It seems a lot of guys reach out before ever checking things on a profile beyond pictures, which you have no public ones. It could be they engage, then go back and pay more attention to the profile.
I see you're upfront about being a BBW, but it could be that, after the fact, they see "4' 11" at 250 lbs" and change their mind about moving forward. It is also very common as mentioned for online interactions.
If you can find and attend a local LS event/party, you may find it way more fruitful than just looking online.
