4 Things to Do If Your Boyfriend is Suspicious by Nature
3. Ask him to get involved in other activities
Often, suspicion arises in one’s mind when one has nothing better to do. Encourage and motivate your boyfriend to pursue his hobbies or get involved in activities that he likes. Ask him to join a dancing or singing or an art class. Inspire him to pursue something he always wanted to and this would keep him occupied in something productive. He would be busy learning and enjoying something else rather than thinking nonsense about you and suspecting you unnecessarily.
4. Suggest professional help
If everything fails, you should suggest him to take professional help. Beware, as this might imply that he is psychologically ill. Depending upon how close you are to him and what kind of a bonding you share with him, tell him that he needs to talk to a professional psychologist or relationship counselor to get rid of his insecurities. Tell him that this would be for the betterment of the relationship, and that you are always by his side.
