If he isn’t making any time for you, you have to tell him this as it’s clearly making you feel unwanted. It’s great he’s trying to be more focused on his education, but if he’s unable balance having you in his life the way you’d like to then you have to think about whether or not the relationship should carry on.

He’s having his fun because you’re allowing him to, he’s already said he won’t leave her and 9/10 men who are in relationship and cheat won’t end the relationship, unless they’ve been caught. You need to cut him out completely. Try going under the no contact rule, because you’re not only having sex with him, you’re still clearly emotionally attached. It’s unhealthy and the longer this carries on.. well the harder it becomes and the deeper your feelings will grow.

Try attending new places…you’re probably running into/giving your number to the same guys. Instead of texting try communicating via regular phone calls.

He might be ignoring you, but it’s good that you want to reach out and apologise. I’m all for clearing things up between ex lovers but I wouldn’t suggest calling all texting. Perhaps an email? He doesn’t have to respond, but just understand and accept what your intentions have been so you can move on.

Sooner than you know!
