Red flags are going up for me! WOAH! Put the brakes on cowboy! You said "just getting out of" and "its been hard" and "tips for getting back in the dating scene cuz your rusty" all in the same sentence! You are not ready. You still have baggage to sort out with in yourself first. You don't want to drag that baggage into the next relationship. That future person don't deserve someone else's left over drama. You need to heal first before moving on to another relationship. 4 years is a long time now a days. Good luck.
