My boyfriend lately has been pretty open to the idea of kids and will happily talk about it. But last night I for some reason felt as if I talk about it too mich so i apologized to him. and he reslly truly told me how afraid he was to have a family.. doctors told him he will die in his 50's (medical condition) and hes 37 atm.... he cried really hard last night and then I started to. After a while I made the bed for him and brought him ice water and rubbed his head. I then calmly told him that I just love him so much and I only want to expand that love (via children) It ended well last night but I am really down... I feel so horrible and I never want to talk about kids again.. I will likely just use some type of birth control. Am I a bad or selfish girlfriend?
