Is he trying to trap me?

I’ve been seeing this guy for about 2 months and he constantly talks about kids and marriage and we recently started having sex. The first time was out of no where so I didn’t expect him to have condoms but after that i thoughtd he buy some second time we had sex we stopped because again no condoms and then he made a joke about giving our parents grandkids. Yes I am not having sex without a condom once was a coincidence twice is a pattern
