Taurus v Scorpio

Im a Taurus female trying to make a decision whether to give my Scorpio ex of 3 years a chance or not. He waited on my for 3 years n never let go . Obviously it didn't work out because he was not ready and sting me for 6 months . Now he said he will do anything to have it back whatever it takes . Before I allow myself to go on a roller coaster again . I wanna know what are the cons for scorpions apart from their silent treatment n otherss . Will this relationship ever work out? I'm talking about a serious level of relationship this time

Strangers helping you make up your mind?
If you have them, don't you think you ought to talk to your own folks?
