I think my boyfriend is depressed that I can't get it together pregnant how can I explain to him just to be positive?

We've been trying for about 13 months now. I went to my ob gyn and she said there should be nothing wrong with me because they ran some tests no pcos, my thyroid is normal, no ovarian cysts, etc I just have high levels of Dheas but other then that I should be fine so I'm hoping it's just stress and that I can go to a infertility specialist. I keep telling him come on we should do it he's like I don't know babe I've came in you so many times and yet your not pregnant we might as well just give up now I'll never be a father I'll just keep on cumming in you and see what's gonna happen. It hurts me to hear those words and yes it's been frustrating to have my stupid period show up and negative pregnancy tests just hoping one day😔
