In love?

I feel like I've fallen out of love with my boyfriend, we're both 21 and live together and I've felt a bit...distant for a while then today I just sort of.....came to the thought of maybe I'm out of love?

We've been through a lot in 2 years (he has a child with an ex whose constantly tried to break us up)

I haven't met his child to this day, and I only ever see him really on a Sunday-which is fine we both work hard.

But Saturday just gone I met a guy -nothing happened obviously (he'd just had a baby with his ex) but it stirred feelings it shouldn't of and now...I'm overthinking everything. Advice? X
