When would you expect your partner to first say I love you?

I’ve been in a relationship for 4mths now.. we spend a lot of time together and everything seems to be going smoothly.

I’m not a person who wants to rush things but I am definitely more of an emotional person and already feel I do love this man.

Not sure if it’s different for men… maybe he is still unsure.. we talk about the future a lot (although I know in a mans mouth might not mean it’s 100% set in stone)

When is normal for a guy to say I love you for the first time? This is my 1st serious relationship since my split with my husband 2yrs ago.. I’ve dated guys but nothing as serious as this.

I don’t want to bring it up to him as I don’t want to pressure him either
