1.How long should you wait before saying “I love you”?
depends on what you think the statement means. Some people take months or even years to declare their love because they believe that saying “I love you” is a big deal and want to wait until they are absolutely sure of their feelings. “However, some people use the term ‘love’ quite loosely; "In this case, saying 'I love you' may seem appropriate in the first few weeks or months."

2. How soon will it be too early to say “I love you”?
It's probably too early to say "I love you" unless you actually know the person very well. This is a sign that you may be confusing love and infatuation. Infatuation is a strong feeling of attraction and affection for someone, while love involves a feeling of close connection and closeness with someone. The feeling of "love" felt in the early days or weeks of a relationship is often actually a feeling of infatuation, Manley explains.

“To truly love someone means that you see them for who they are and are willing to accept them with their strengths and weaknesses; this type of love cannot arise from a series of short dates

3.Should I say it first?
Basically, if two people love each other, it doesn't matter who says "I love you" first. If you're not sure if your partner feels the same way you do, you can still tell them how you feel, just remember why you're doing it. If you just want to let them know where your heart is and don't mind whether your feelings are reciprocated, go for it.

1.You feel it bursting out of you.
