Clingyness and obsessive ness is very unatractive, and will hurt your relationship. If you start acting like you doubt your partners love for you that will hurt them deeply because you sound like you dont trust them- If they confessed their love for you and chose to be with you that means that they do love you! Acting like you doubt that would be practicly calling them a Liar, but if you feel that they arent giving you enough love or feel that they think they need to conceal you than somthing is wrong. If you want more love or need more love and reassurence, than strait up, tell them! You both need to find a way to solve that issue and talk about it rather than avoiding the question. Ive made this mistake before and it never ended well. Dont make my mistakes kiddos.
