Here is the problem. Your boyfriend is not a legal title holder to the property and has not been named on the loan. So on one hand, he is paying towards a mortgage to which he is not obligated to pay and on the other hand, you are getting the benefit because you hold the title. Placing him on the title alone with you is not going to help, because a) it may accelerate your loan and make it all due immediately because there is likely a provision in your name to prohibit you from transferring it and messing with the security interest the bank holds on that property and b) it doesn't do anything to require him to pay on the mortgage since he is not obligated to pay. You would need to consider whether it may be more beneficial for you to transfer in joint title and refinance to ensure both of you are on the title and on the mortgage loan.
