To be honest with you, you are the source of the problem
How would you keep having opposite sex as friends when you know u are in serious relationship?
How do you think he will believe you are a changed person when you keep adding to your male friends?.
The same way you were carried away with the business Olumide introduced if it were to be true would have been the same way you would have worked out of that relationship if he sweet talk.
Thank God your boyfriend is very calm to have been able to tolerate things all this while but I think there will be a big problem if you continue with this habit of adding and given unnecessary chance to opposite sex.
How would you feel if your boyfriend is the one doing this?
please try and limit that habit if truly you need a "home" for yourself. God bless you

please my dear brother, run for your life
