Omg! Is there someone who can give me good advice? Please?

im a mother of 3.. i was kind of in the same position as you but he was military not a dr. i had 2 kids at the time and i moved in with him. my advice to you is just make sure this is what you both really want. i mean think how its going to impact your kids if your relationship doesnt work. i thought about that for about 4 months before i decided to move in with him and he is now my husband and the father to my 7 week old baby... also since you met him online just do a backround check make sure hes not hididng anything from you... and go from there, sometimes you have to ignore your family and do what you think is best for you.. i did any my family couldnt be happier
