There are plentttyyy of people who have children after 26! Just because you don't party, doesn't mean that's a valid decision to having a child.

The most important part is cultivating your relationship with your boyfriend if you intend to have a child with him. You need to make sure that you actually want this individual to be in your life 10-20 years from now.

Since your name is "brokenandalone" I think looking into therapy would help. Especially if your biggest motivation for having a child is to feel less lonely. Or to feel like someone will unconditionally love you?

If you believe you have 3-4 more years for the best chance of having a child, use at least half of that time to get to know your boyfriend better and create a stable foundation for your relationship.
