Search Results: ex really upsetting me

So me and my ex boyfriend broke up 4 months ago
But he wanted to stay friends
So he's always trying to stay in touch by messaging me nearly everyday and sometimes randomly calling me to just talk
And wanting to hang out every week
Since I still have feelings for him, I agreed to seeing him every week

But 1 month ago I met this cute guy
And started seeing him as well
We hooked up
That guy gave me a hicky
I went to see my ex the next day
Then my ex got upset and hurt when he saw the hicky and so he figured I was seeing someone else
So next day he cut contact with me and blocked me on everything

I didn't try to contact my ex for a whole week
But that week made me realize that the guy I was seeing was just a rebound and Im still in love with my ex
So i decided to message my ex via whatsapp (he forgot to block me there)
Expressing how i truly feel and saying that i still love him
Then he called me up saying "I was waiting for you to message me, I realize I can't be without you"
Then we met up next day and we got back together last week

Do you think he missed me during that week?
Or dont really care?

So I’ve made a promise to myself to stay away from f@ckboys just focus on college and work. This one guy I know a while has been asking me for a date I agreed cause I honestly thought he was a nice guy. Anyway it’s the night before the date, I noticed two blonde girls he constantly seems to like on Instagram and it’s annoyed me cause he reminds me of my ex. Always having a girl on ig as a backup plan. And I’m also upset because these girls are both 22 and 20. And I’m 28 so I feel kinda shitty that I’m getting older. This guy is 25 and I kinda felt that I shouldn’t have agreed to go out with him in the first place because of my age. I went through hell with my ex and I’m terrified of wasting anymore of my time,

So I felt for both our interests if I just cancel. I need somebody that’s probably not on social medial (impossible to find I know) and maybe a little bit older than me. And he probably should just stick to these girls. I’m not jealous of them like they’re stunning and I don’t seem to be his type. All the girls he follows are tall, blond and slim. And I’m brunette, small and am quite filled out on the bottom.

I tried to cancel and he wasn’t having any of it. So I really don’t want him paying for me on this date and I know he’ll try too. I don’t want him to think I’m using him for free drink or food. Should I try cancel again or just go on it?
