This your boo seems to be an unrepentant play boy. This is the kind of man that will cheat after marriage.
There is nothing wrong with what you did by getting your own apartment, He's just a stupid man without good morals.
Poster it is in your hands now to choose what you want.
Two options here
1. If you are desperate to marry & you can bear him cheating on you after you both are married then continue & speed up the marriage plans.
2. If you cannot deal with a cheating husband,anyhow husband with no good morals,
& ultimately if you can deal with having to wait for a prince charming which might/might not take a lot of time to achieve,then ditch this man & move on with your life.
