The unknown future

My boyfriend and I have been together for two and a half years and we had a serious talk last night about marriage and when I graduate (in two years) we should get married since we created that plan. But now talking to him he was hesistant and worried a lot about financial things and said well maybe you can have a stable job so if we get married we are good financially. But I thought love is something that you would do anything for meaning getting married. The more we talked he seemed hesitant and I don’t want to waste my time. He’s 25 and I’m 22 I’m just not sure what I should do. He has a house under his name almost paid off maybe he just doesn’t want to be with me in marriage.. am I just thinking too much?
