Can’t stop masturbating over my ex

She is my baby mother - 7 years we was together.
We are learning to co parent and it’s only been 9 months since we split.

Since then we still rarely have sex as we have a lot of attraction to one and another. We both don’t have anyone else but I know she is much healthier than I am in regards to healing and also has tons of men liking her social media posts. ( old hook ups - flings etc )

Where as, I am absolutely not wanting anyone else, I look and find some women attractive but I just don’t want to have sex or hook up. I want my ex.

Is it because I am still in love and have so much attachment that I keep masturbating over her?

Even when we are together and we are affectionate etc I leak so much pre cum. Like I’m a teenager.

I get home and masturbate immediately. A few times. Over our old sex tapes and pictures.

Sometimes we are in each others company and I get so hard, she knows this as we joke about it, even when we say bye and she kisses me. I’m rock hard.

I do try to initiate sex but she’s right that it does confuse things when we are trying to heal and break up.

I find myself becoming insecure and jealous, I have started to look at the men who like her posts and question are they an old fling or connection?

I compare myself to them. What do they all have that I don’t. Why does she keep them on there? Is it for attention - to keep active so when she wants she can hook up.

For me - I have no one on my social media when I’m in a relationship - if I do that’s because I am single but I delete them all when I am with someone.

I am extremely devoted, faithful and loyal but now all these doubts are flooding in that she kept all of them whilst we was together - some are from the year break we had - but why keep them?

My head is a mess at the moment and I keep finding myself seeking her approval, her love, I want to be wanted by her and I am so attached still.

I just got back from a weeks vacation.

I got hit on a fair amount of times but I didn’t give back any vibe other than respect that I’m taken and not interested even though I’m single and could have easily hooked up.

I just don’t want anyone else.
