<human>: He says he loves me he says he misses me a lot. He's said a lot of things that seem genuine. He said he made a mistake leaving me and he never stopped loving me. 

But I'm worried. He's not the kind of guy who needs a girl. We first broke up because I would get jealous. But now I keep thinking he's with me because he couldn't get with any other girl. His first girlfriend has also found someone new recently. Maybe hes come back to me to spite her? I can't say this to him because one of the reasons we broke up was because I would get jealous about her. Am I being unreasonable? Maybe he's just lonely and wants to be with someone because she is with someone.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Why has my boyfriend come back? Is it because he genuinely loves me like he says or is it because hes just lonely.
