By all means possible get rid of tension and discomfort. It can be somewhere deep inside, however your behaviour and the way you act might betray you. Simply relax and be yourself. Understand that you are dealing with a friend, not a lover.
the quickest way to find out whether there is something suspicious going on between your partner and his female friend is to talk to him about the problem. Let him know how you feel and ask him to explain the moments that seem to be unclear to you. Give proofs of your suspicion if any. It is absolutely normal to talk about such issues.
Phone calls and messages
If your beloved receives phone calls from a female friend and you want to know more about that person, just go ahead and ask him to tell you about her. Do not torment yourself by negative thoughts.
Pay attention to the way your boyfriend/husband treats the woman you are worrying over. If she is treated by him just like a good buddy or a male friend, then there is no need to get nervous if you do not notice any flirting between them.
if you don’t want to meet one-on-one with her, you can invite this girl to hang out with you, your partner and other friends. If she also have a partner, you can also invite him. You will see what she acts like when she’s around your boyfriend. Be sure to pay more attention to her body language, it will certainly give it away.
Do not pay attention
you cannot make the person disappear. However, you can always ignore those whom you dislike. Do not pay attention to your partner’s female friends. If they irritate you, never let them know about that. Be neutral, but never rude.
