Truth of my 'loving' non bf... talked to my bf's ex gf.

So somehow I got to talk to my bf's ex gf on skype.
his ex gf told me..
'he is really a sweet guy... Romantist.... I've never met anyone who I share so many things in common. He once cried for me... and I felt so bad to make him cry'
yyy: why did he cry?
ex : I cheated on him
yyy: oh...

she has known him for 7 years, and she told me his relationship history, and the truth is that

he is EXACTLY same to ANYONE he likes(he easily likes anyone, I know that). He gets infatuated with her, super loving, supportive, admire, faithful, do the exact same activities(like he did with any other ex) together...

I guess that every people might be more or less same toward their date,
but I thought he is special because he is really obsessed with me, he needs me 24 hours, admire me to extreme, dedicated, enormous love bombing, has been so for more than a year.
But all those sweet messages and everything,
has been sent equally to any woman he liked, he has cried for every woman for same reason, and he liked so many women, always to equal degree...

and the thing is he knows it. He is like 'i like you well but my life/happiness level won't change at all even if we break up. I can be 100% satisfied/happy without a girlfriend thing, or I'd just get to like the next one I date.'

You know he is really a nice boyfriend, very loving and faithful and devotional,
but you think this is uh...
umm... something like love?

so far my exs were all like 'i was never in love with a girl this much in my life'
so current bf makes me feel kind of... I don't know, in a way secure (it doesn't matter who I am)
in a way insecure. I'd say more of a secure.
