Christa,Congratulations on your pregnancy. I am sorry someone felt they had to spread gossip as this person does not have your best interest at heart. We are all seen talking with friends that may be of the opposite sex but that does not mean we are involved in any personal relationship with them. If your significant other claims he did nothing wrong then do take him at his word if you believe in him.
Pregnancy and hormones can mess with our minds so try to pull back when the "what if?" thoughts pop up and you begin to doubt and think of all the good in your life. Remember why you chose this man to be your partner and now you will soon be the parents of a newborn. Be kind to yourself and know that your feelings are normal as long as you can keep them in check.
Keep on talking with us here in the forum and know we are here to support you.
Kindly,
Kitt
