I'd beg, borrow, or steal the money to see a solicitor if that's at all possible. Because good legal advice is always worth paying for, even if all they do is say it will be clean and simple, it's OK do it yourself just do XYZ. At least any doubts, questions, and possible pitfalls will be removed.
I think a few people around me think I have become hard......
Of course you have. You've had to become 'hard' in order to move forward. What the hell did they want you to do, melt into a puddle on the ground? And don't think of it as 'hard', what you are is STRONG, even if it doesn't feel that way in the moments of tears. Tears don't mean weakness, even the strongest shed tears. Tears are simply a way to release emotions that might cause us to weaken. Tears can actually keep us strong.
seeing him hurts so much and daily its just too much
This will lessen in time. But if you can get the ball rolling on being able to get him out with the tenancy papers that will lessen the amount of time you have to put up with him. Seriously, he's probably not in all that much of a rush or he would have left by now. Why should he be, in his mind he is in the catbird seat with all his home comforts in place. Even if you've stopped his home comforts, he still has a roof over his head and can do as he pleases. That's probably enough to keep him there indefinitely.
