If you try to stay in the United States and adjust your status to green card holder (AOS), the timing of your VWP entry may raise some questions about whether you misrepresented the purpose of your entry, which may in turn cause some problem with getting your AOS application approved. This answer assumes that it would even be advisable/possible to reroute I-130 for in-country AOS processing after you have already indicated that you would consular process. Some may disagree, but I believe that the least risky option is to continue on the consular processing path as you have already started down it. Schedule an in-person meeting with an experienced immigration attorney before making any decisions.
My colleague is correct ... using VWP/ESTA can be a big problem.
Meet with an attorney before filing any more papers.

The status of an applicant with VWP is somewhat shaky. A VWP visitor gives up the right to appear before an immigration court. This means that the DHS can detain and send a VWP participant home if a visa adjustment is denied. This can cause even more complications once consular processing begins.
Although it is unusual to deport without a hearing, this has happened to a few VWP visitors. Many VWP visitors have adjusted status who have not filed an I-130 before entry. It is also true that others have elected to successfully adjust status in the U. S. after beginning the process abroad for various reasons. Whether to change your mind at this point should be carefully discussed with a competent and experienced immigration attorney. Good luck.
