You are correct- healing and feeling better is important before you jump into any new situation/relationship.
You also seem to have realized that the prior relationship had not been a good and healthy one. What you may be missing in that person is not the individual per see (but your hopes that this person would have changed and acted better)
People usually find themselves in vulnerable relationships when there may be some unresolved issues from past relationships (Such as having been rejected by a first love, a male role model ex father, teacher, etc) and subconsciously getting attracted to people who remind you of that (in a way trying to remedy and fix the situation from the past)
A man should never pressure you to the point where you feel pushed. He should respect your wish (as to why he can not respect that the possibilities may be many - he is just a self serving individual, he's set on getting what he wants regardless of what you want or are comfortable with, he lacks social skills to figure out that he is rather pushing you away by acting in this way,etc.
Do not do anything you're not ready or comfortable doing. You have already been disappointed and don't need any more of that.
