Hi there....
Something else to consider is you may need time to heal for awhile before dating just yet. This man you described could be a rebound relationship for you since your still separated & the divorce isn't final yet. You may need to do xtra self care during this stressful time in your life (ex. Get a massage, read, take a bath, etc). You can then turn your wounds into wisdom as Oprah would say

. As stated above until your current relationship is healed w/ counseling of some kind & time then it will be much easier to have your personal emotions in check to move forward & date again. Please know you are loved very much by our Father in Heaven, we do have agency & bad things happen to good people as part of our life so we can learn & become stronger & wiser through our pain.
