Is it normal to have feelings of quilt while trying to look for someone new?

What you feel is normal to your own case, give yourself some recovery/ healing period, so you don't get into another relationship with all the emotional baggage, have fun , and if you do date, take it easy, don't get your hopes up too quickly. After all, everything good comes at the right time if you don't rush it. Also forgive yourself and learn from your past experiences, so you can do better next time. Life it's like a big wave, you will fall many times, until you learn how to ride them, hey...even professional surfers fall!
