Talk to her soonish, make the decisions with her
If you go ahead, do not put his name on the birth certificate, yours and hers only, there is a legal reason behind this, what you tell the baby at a point in life is the truth but you will always be dad --- you will want to keep the OM out of your lives. Do not agree to a DNA test he can’t force you. The child is yours no one can prove otherwise unless you let them.
All the above assumes she is prepared to stay married to you.
Good luck ..
