Is some jealousy normal in a relationship?

[NotReadyForThisX2]

Had a incident with Dp which brought back some issues we had at the start of our relationship.
It got me wondering if a degree of jealousy is normal in a relationship and if so is it just how it's dealt with that's the problem? I think I'm quite easy going and we have a trusting relationship for the most part. I don't worry about him going out, having female friends or feel the need to check his phone or anything. But likewise Dp hasn't ever given me any reason to worry.

Dp does get a little jealous though but it's something I thought was behind us. Now I'm worrying a little that he isn't really as ok as makes out.
Has anyone dealt with a jealous partner successfully?

Jealousy as a feeling, sometimes OK. Jealousy as a behaviour, not OK.

What is it that you / he does that you would describe as jealous?

My ex was ridiculously jealous , he didn’t display this all the time , sometimes he would no speak to me for three days at a time simply for changing my display pic on social media and a guy “liking” the pic .
It was random as othertimes he wouldn’t display jealousy at all which makes me think he was attempting to keep a lid on it , which he managed to do but then it “escaped” every now and then .
Long story short , he was the one cheating on me ....projection is often the reason behind spurious bouts of jealousy in my experience.

But what was “the incident” that introduced some jealousy at the beginning of the relationship? We will be able to advise better as to whether he is being jealous for no reason or if it’s for something potentially understandable to an extent??

I think you need to give more detail, a "little jealousy" needs definition.

Depends how it manifests and what he expects you to do about it.

If he's a bit insecure but knows he's being a nob, and doesn't expect you to take responsibility for his feelings or change your behaviour then meh. If he expects you to pander to his jealousy, explain yourself and not do things, then whoop whoop red alert.

I know he can be a bit insecure but thought we were past that being a issue. Now I'm actually not sure. I posted another thread about something he said yesterday and it's just making me wonder if that jealous nature is always there somewhere and if that's quite normal in relationships or something to worry about.
I guess the fact I'm asking means it's something I'm worrying about though and really that's all that matters. I was probably hoping posters would all say it's normal sometimes and everyone has jealous moments.

I don't think it's normal. It shows a lack of trust - which can arise because of something you have done or something someone else has done to him.

If the former, you both need to work hard to rebuild trust, if the latter, he needs to find a way to move past it. I don't think you can have a good relationship without trust on both sides.

I've never cheated on him. His early jealousy was around other men though and he worried I'd been talking to someone else or would meet someone else.

So - does he treat it as his problem (given it's based on nothing but his own insecurity) or does he treat it as yours to handle?

It doesn't really cause problems @category12. It's not like we argue about it now or anything. I'm maybe being pregnant and hormonal but I'm just wondering about some little things he says or does that I've not picked up on before.
