You need to be sure you see a future with them, no matter how scary a long-term commitment might be. It’s not only unfair to your partner for you to be unsure, but it’s also unfair to their child.
Take time to look inward and ask yourself if this is
something you can handle. Ask yourself if your heart is big enough to
love someone else’s child? If not, this isn’t the relationship for you.
You grow up really quickly.
You put aside your selfish needs and the life you lived before for this child and their parent. You give up the bar or a night out for a night in. You’re staying in and watching Frozen for the 5th time this week and you wouldn’t change a thing.
The child always comes first.
That child needs more love from his parent than you do from your partner. Read that again. Read it again, until you understand how important that is.
A good parent will never choose someone over their child. You don’t give your partner an ultimatum because you cannot handle the situation.
You are a grown adult that does not need constant attention. This child needs their parent’s love. Your partner deeply loves you, but if you loved him and his child you’ll understand that you never can interfere with their relationship.
