Yes you are moving really fast. Don,t rush into it and regret.

Get to know yourself. The first months into relationships are the pretending stages( this stage is likely unconscious). You try to impress and what have you.

Start with Engagement. Spend quality time together.

Yes. I think you are moving too fast. I don't think you should stop talking about marriage. But instead of gunning for the wedding, why don't you start planning for the marriage? Read some books. Attend a marriage conference. But also be sure you are talking about other things instead of your future. Can you talk about the here and now? Because once you're married and have kids, then what will you talk about? Marriage is hard even when married to "the one". But spend some time working on the relationship and making it stronger.

There's no need to rush things if you already plan on spending the rest of your lives together. The problem with rushing in with such passion is that it doesn't allow for adjustment and it can make events that pop up more difficult to deal with. Focus not only on each other, but on the process of combining your lives and preparing for the future. Or try setting a time limit and build up to that point. Like, in a year you will start planning the wedding. Then, you have the time to get to know each other better and you have an exciting time of event planning to look forward to together.

New love is very exciting and the emotions you feel are very strong. Why rush into an engagement? I can see no advantage to getting engaged quickly. It just makes things harder if the relationship doesn't work out. Give it some time and take things at a comfortable pace. You can profess your love and make a serious commitment to them prior to a formal engagement. Consider a pre-engagement or commitment ring as a sign of your love.
