Why do I feel like I'm cheating on him still, even though we broke up months ago?

A sense of loyalty and attachment may last after you break up (especially if you've been going out for some time), it's perfectly normal and okay to feel like this! Just don't rush into anything with someone else to just 'get over them', it will just add to the feeling of cheating.

Well thats simple, even though the relationship was long over, your heart feels like you're still tied up to him. And no matter how much time passes, you continuously keep on thinking about him and about what you had with him as a couple. Which is why, then when you start seeing other people, you feel as though you're cheating on him and the new relationship with the other guy would feel wrong.

the remanant feelings and emotional conflicts will be there; like a shadow following you around. the connection will linger even after separated, so will the familiarity and clinging to "used to"--everything new will seem different and we usually don't respond to change in the best possible way. your previous relationships will establish its own habitual patterns of behavior (the how it "used to" be as mentioned above), and also the conscience coherent best accommodate the relationship. this conscience will accompany us even after we move on. As they say: its not that you can't move on with a new stranger, its the previous relationship that is deeply integrated within us, shaping how we behave, unconsciously rejecting another "stranger", an invitation to a date, initiating another romantic affair. on a bright note, our conscience rejecting the idea of someone new shows that we have loved, hurt beautifully, and is imprinted by love--it shows that we are humane and vulnerable. now, we also wrestle with self-inflicted pain. breaking up may just be a scar, holding that much pain. we may take the scar and irritate it, scratch, press on it, not letting it heal. this could be a result of past trauma where we unconsciously reflect how people treated us back onto ourselves (self degradation, detachment, anger etc.). It could be to verifying the significance/meaning of your past relationship through emotions--for we are afraid to not care and not feel. It could be to gain a sense of control, or perhaps a pleasure (pshh innuendo implied). anyways!! reach out to me if you need to talk. yes they all say this, ridiculous as it sounds now, time will ease the pain. the tides of time will carry you farther away from the thing

The emotional break up takes longer than the physical one. That's why exes don't usually become friends right after the break. There are left over feelings, memories. And it doesn't mean anything aside from the fact that he meant a lot to you and it's gonna take some time.

It could be that you still feel like you have a connection with your ex and still have an emotional attachment to him, especially if it was a long-term relationship or a relationship where you felt very deeply for him.

because you are still emotionally bonded. feeling this guilt is extremely unhealthy because it means that he has more of your mind occupied than he shoud have

You can be feeling like that because you really cared about him and the feelings are still there and some of the wounds are still fresh. You shouldn't feel guilty, its jut sometimes the normal ups and downs we feel when going through a break-up.

Maybe because you sill haven't moved on. you still have feelings for him. And somewhere inside you want things to work out.

You might have broken up physically but still be mentally and emotionally attached to him. These attachments take time. Give yourself some time and explain the change to yourself and you'll get over it.

After coming out of a relationship, it is always hard to completely move on. The only thing that can change that is acceptance and time.
