On Valentine's Day I need to tell my girlfriend that I love her.
Is there a reason you are sharing this with me?
Just a reminder to myself to make sure that I tell her.
Oh okay, well that's fine. It's good that you want to remember to tell her you love her. Everyone should find ways to tell their partner that they love them.
I'm going to tell her, but I'm still thinking of something sweet to get her as well.
I think it's lovely that you care about your girlfriend and are taking the time to making sure that the day is special for her. It's good to show affection and love towards your partner, as it helps strengthen the relationship.
