is this trapping him?

my bf and I have been together for almost 4 years now and we've lived together for a little over a year. Latley I've had baby fever sooo bad and it's all I think about. He wants to wait until he's making a little more and until were married but.. sometimes he dosent pull out and I have no form of birth control or we dont do condoms etc.. it's not trapping him if he's the one that chooses not to pull out right? Edit: yes he knows im not on birth control and we have talked about if i were to vet pregnant and he just says that he would be supportive but i guess you never know until it actually happens and I dont see the need to tell a grown man that having unprotected sex can lead to pregnancy..
