Having been in a similar situation as your BF in the past:

- Do not put him on the title at all. That is a headache for you.
- Your offer to cover the mortgage and split utilities was wonderful, and avoids the negatives of financial abuse. (When someone rents from their partner, it generally create a situation of financial abuse, because one person can exit the relationship having made money off the other.)
- Consider giving your partner a "living estate", where he has the opportunity to continue living in the home if you pass, before the house goes to your beneficiaries. If he is your only beneficiary, you can will the house to him too.

If he is pressuring you to do this in order to save your relationship though, this looks like a red flag and you may want to re-evaluate everything.
