I have gone over what you have written. This is not an uncommon case or issue for me. Many couples come to me with problems similar to yours. Now as I have said before if you read what I wrote previously on this website, if you return to your boyfriend at the end of the day, then he need not worry. My husband and I each have certain thing that we take time to tell each other. A relationship consists of two individuals, not more. In today’s time people may try to change your words and create problems for your relationship. Your boyfriend must come to terms with acknowledging that nothing occurred between you and those certain males. After a year, a certain trust develops. You or him may not be able to see it, but it is their. As you have stated, you have been together for 15 months. He must understand if you wished to be with other males you would not have remained with him for that period of time. Establish certain rules, not hard restrictions. Communication plays the largest part in every relationship. I have seen many problems and situations not only as a couples therapist but in my own marriage of 35 years. I do not know all of my husbands co worker or friends and it is the same for him. You may think that I am merely telling you these things easily but through 35 years I have been in your position multiple times. We maintain a balance among us. We come back to each other at days end. You must be strong as a couple. Rise above these situations and above all, communicate. You both have a long way to go. Do not break up of issues as such. Build a protective wall around your mind and bodies. Do not allow anyone else to enter your relationship. Communicate and heal together. Spend quality time with each other and grow. Pay no heed to these problems. I always remind all my couples that if they are to fight together, nothing will be able to stand between them.
In the dating world, I often see that one of the most common reasons men pull away is that they find the woman to be challenging, and she gives in because she likes him. She starts settling and making excuses for his lazy or inappropriate behavior. There are many times I see a woman dating a man, and he shows all the signs that he is not ready for a relationship with his behavior and his words. Instead of pushing yourself towards him in the hopes of changing his mind, I believe the right thing to do in this situation is to dig deep into your feelings. If you can control your feelings by maintaining a friendship, then go for it. (And I’m not talking about being “friends with benefits.”)
