Relationship experts Dan and Jennifer addressed a letter from a worried boyfriend concerned that his girlfriend may be practicing unfaithful behavior. The girlfriend went out of town for her birthday and did not invite the boyfriend along. She did not call or text him the entire day, which of course threw up red flags. Dan and Jennifer advised the boyfriend to calmly approach the situation and explain to her how these actions made him feel. They stated that the girlfriend may be backing up from the relationship needing space or that she may have hooked up with someone else. They strongly discouraged abrasiveness when dealing with this problem.
