My(f20) bf (m21) is requesting a DNA test on our child.

Honestly I don' t really care which he asks for a DNA test. What I care about is the reason behind it. He keeps on saying that it is because it' s to get him and our child. That he doesn' t suspect me of cheating on your pet but that he needs the particular reassurance. At first I informed him it was fine, that I didn' t care. Then I thought about it for a few times and now am starting to get really upset because I got done nothing for him to think our child isn' t his. He cheated on me before I discovered out I was pregnant, and his reasoning was because I had been getting to close to a friend associated with mine who was a female but additionally a lesbian… I made a decision to work things through this. Now I just feel like this individual thinks I' m cheating on him or had cheated on him and my child isn' t his. He told me he just asked because he saw the Facebook post saying that if you ask for a DNA test the child' s mother shouldn' t be offended unless she was doing some thing wrong. Now that I have changed my mind he will keep telling me that I' m making myself appear guilty. Any advice?
