ex gf

So, lately i’ve been very kind of jealous of my boyfriend’s ex gf.

She’s from another city (so he is, but he came to my city so he could be with me, and also practise the sport he loves) . He told me the other day she wrote him a letter, so he read it for me, and said stuff like “our lives had move on but you will always be my red thread” the red thread is a belief that tells that if you met someone and you somehow separate, destiny will put you both together as if it was ment to be. So that ir really hurted, and he saw it hurt me. I dont thinks that’s jealous but its not cool to know someone loves your man too, right?

Today i was on facebook and saw he liked all her shared post, and he never do that to me. I hate this, i don’t know hot to feel, i hate being jealous, but what if they do have that big love? He refuses it, and i believe him when he does, but u know destiny ..

I love him so much, and i know he does too. On vacation he even reject her on a party (cause she wanted to kiss him) and she added that on the card to, asking forgiveness (i read it)

I hate being like this .. any sugestions?
