This is late, but I hope you read my comment. Your boyfriend being an INTP does not mean that he's not capable of being madly in love with you and wanting to spend the rest of his life with you, and seeing that as a real possibility. If he DID see it as a possibility, he wouldn't react the way he does when you talk about commitment.
You cannot "fix" him, as much as your kind ISFJ heart wants to. This relationship will never be fully fulfilling unless something changes drastically on his part, and after 7 years of no changes, even after you've been clear about what you need and how he can help to give it to you, it's quite clear it won't ever change.
Don't move out in the hope of it serving as a wake up call to him. You need to move out and end the relationship because he does not see a future with you. He is not invested enough to do even little things that bring you security and comfort and joy, like simply remembering to tell you he loves you without you having to ask him to. Part of being in a healthy relationship is recognizing your own shortcomings and how to best communicate with your partner. You do things for him because you know they make him happy.
Most importantly, though, stop wasting your time. You've spent 7 years with him and now you ask him to just tell you if he wants to commit within ANOTHER 7 years, and even then he can't have a civil conversation and tell you he loves and cares about you and sees himself spending the rest of his life with you, even though he's not yet ready to propose or get married? He doesn't know what he wants and moreover, he knows you want that commitment. He's not invested.
You've spent the majority of your 20s with this man. I'm sure there are beautiful times and you've grown a lot as a person. You can and you will find someone more compatible. It can be so hard to leave after that much time, but you need to. You are capable of being loved and many, many men are capable of loving you in the way you need to be loved, and will rejoice in doing so. Rip off the band-aid now and end the relationship before you waste any more time, because this isn't fulfilling for anyone and it never will be.
