Fallen out of love?

So I've been with my boyfriend for 9 months now and I love him to bits, at least I thought I did... there's this new guy and we've only been talking for a couple days but it feels like magic and spending the day with him made me feel so good and I've been secretly competing for his attention when I should be trying to get my own mans attention. I don't know what to do 😩😩 pls help me
