trying to make someone jealous
I think to this one lies in your original question. They are your EX! Not your problem and you have no place to call them out. Move onI say you punch him in the face.
husband happy after seeing ex girlfriend
If you are still with him and he is also seeing his ex then I would leave him. I realize that may be hard but if he is seeing someone else he is cheating on you and you deserve better. But if you believe there is nothing going on between them then you should make your feelings clear that you do not want him seeing his ex girlfriend - if he chooses to ignore the way you feel then unfortunately again you will have to do what is best for you and leave. Either way the outcome seems to be the same.
'Ex' means the relationship is over and the woman you are dating should not be seeing her ex at all! It is very rare that two people can sleep in the same bed with one naked without becoming a sexual act and she is stringing you along. Do not enable this behavior and let her know in no uncertain terms you are not putting up with her seeing her ex and she should be moving on from her ex. This is a new fad of exes as friends; in fact, it is just an excuse to see each other if their other relationships fail. The only time two exes should ever see each other is if they have children and are on a custody basis of those children.
* If he is in contact with his ex while being with you then anything is possible. Unless there are children involved where he has to see his ex to see his children, then he should have moved on from his ex. If he is still seeing his ex tell him it's either her or you. Never take a back seat to another woman in regards to your mate. Don't blame his ex, blame him!
Stop seeing him! He obviously is not over his ex.
Your boyfriend can't possibly be in two places at the same time during the weekend so if you don't see him on the weekends it is possible he is seeing his ex. Also if he lacks phoning you like he use too or is seeing you less than he use too. The best way is to communicate with him and ask him straight out if he is seeing his ex. This does not mean he will confess and may lie about it. Tell him if you ever catch him it's the end of your relationship.

when did you break up?
'Ex' means it's over! This ex shouldn't even be in the picture. Some people in this new generation feel that you can be friends with an ex (only a very small percentage can do so) but most people want to move on in a more positive direction. Say no to him and let him know you are a one man woman and nothing else will do. If he doesn't get that then tell him to get rid of the ex, but, if he keeps seeing her as he has been then it means she will always be a wedge between the two of you.
drop her doll it wont be worth it if shes still in love with her ex and is still seeing him cause if she cared about you she wouldn't see him in the first place
Stop seeing them. Stop going having them over/going to their place. Stop crawling into the same bed. The list goes on and on.
