I hate to sound trite and cliche, but when it happens it happens. I was thinking I was ready for 3 years, but I really wasn't. As a matter of fact, we stopped dating for a while and had some time to both really reflect on what we wanted...ok, so we didnt' stop seeing each other, but we were not a couple and we didn't live together, we really didn't see each other much,but I digress. We finally decided to give it a "real" go after some time...and pow, within 4 months we're engaged.
I thought I was ready, but I wasn't, now I know he's who I truly want to be with.
Maybe your guy just isn't ready, and his family pressuring him isn't going to help. Besides, you're young, what's the rush? If he's the guy for you, you've got the rest of your lives together anyhow.
