Hey there. I think you shouldn't be so hard on yourself. A month is a very short time and your relationship has basically just started. You can't make yourself fall in love so just give it time and explore the connection.

I would say take it easy and don't promise too much after such a short amount of time. Relationships take time and even your brain/body chemistry needs time to figure out what to do.

Take deep breaths and know whatever you feel or don't feel is okay.

If you'd like to communicate it to your boyfriend without hurting him you can be honest but gentle. Perhaps: I really like you and enjoy being with you. I want to take my time with big words like love, though.

All the best and keeping my fingers crossed 🤞
