I think wanting to find one girl is fine but the problem I see is this:
A healthy LTrelationship requires you to be truly, emotionally healthy. If this isn't the case, then sosuave, asf, etc. are only going to bring you into a string of 1Mo-1yr. old relationships that always descend into darkness and leave you feeling blue and wondering what went wrong.
When the desire for bonding is too strong it can be a really strong repellant of women. I think this is what most commonly is reffered to as neediness... not being able to go a day without seeing her, calling her 6 days in a row and talking for 5 hours per session, clinginess, etc. These types of things can be a real problem. Just knowing about it isn't enough, it's like guys who know they shift weight from foot to foot but still do it during speeches anyway.
Even if you develop a good cover for STRs, in a LTR sooner or later you will let your guard down. You will get comfortable, and you will act like your core self. Is that core self ready to be revealed? Is it a stable, healthy core that's happy to meet the world? Unless these problems are addressed, it will be the demise of an otherwise functional relationship.
