I broke up with my boyfriend

Hi I broke up with my boyfriend a few days ago and it has been hard. Mostly because he lives w me so it’s going to be a few weeks before he can move out but I truly couldn’t wait any longer. He wanted me to wait until after his bday but I feel like that’s just selfish to be with someone you know you don’t want to be with. I haven’t been happy in the relationship lately and I am kinda scared that I may regret it because he was so good to me I just don’t see myself in a relationship right now, especially with him. Please help/give me a pep talk because I am in the dumps rn feeling guilty and sad about having to end it.
