Past love quotes show that this subject can cause bittersweet emotions to surface. When you think about a past love you may remember the good times with joy but also feel sadness or regret about the ending of the relationship. A new significant other should never feel threatened by a past love because your previous experiences have helped shape you into the person that you are today. If you had not had the past love then you might be a different person, and your current love may not have fallen for you in the same way. Sometimes a past love ended badly and you may still have anger or resentment. If you find yourself in this situation then it is important to deal with the emotions left over from the past love so that you can finally heal and move forward.
