I just want to feel ok

So i got out of a year relationship with someone who lied to me and mistreated me and everything whenever possible . Then a guy i had talked to before this abusive relationship messaged me again and when we are together he makes me feel like I’m his world but between his work schedule and my work schedule we get like no time together so I’m constantly questioning him and his love for me . It sucks that walking into something so good makes me feel so horrible . I feel like I’m going to run him off but i don’t know how to just talk about it . This sucks .
