Am I wrong for giving my boyfriend a time limit?

Me and my boyfriend have been on and off for the past 4 years The last time we broke up, we decided to be friends for a little while before we got back together. We are back together now but I told him if we broke up again we would be done for good because I’m tired of the on and off relationship and I feel like our relationship won’t have any progress if we keep being on and off and I also gave him a six month time limit for us to get engaged move back in together and to start trying for a baby I’m really tired of waiting for things to happen am I being too pushy and should I just let things happen naturally
