Just looking for a bit of advice

Me and my boyfriend where together for about 8/9 months which yeah I know it’s not that long !haha but we lived together and spent every day together (that’s probably how we grew apart) but basically I feel as if he was just always interested in other people and it wasn’t going to work ... I started a new job and met this guy (a lot older than me!!) We would talk in work and I could feel myself flirting with him . I started having dreams about having sex with him and i would wake up really turned on , and I don’t normally get turned on much but even just looking at him I would be 😂, just because of how I was feeling I finished with my boyfriend 2weeks ago because I just felt like maybe if wasn’t him not happy in the relationship it was me , but I spent the weekend with him and his daughter and watching him with her there so cute 💗 I’m just wondering if yous think i should wait or go for it and continue to see him
