When she asks you who are talking to or who you have been talking to over the phone, you have to be careful how you respond. It does not in any way imply tha she is suspecting you, she might, however, br suspecting you.
When asked such a question by your partner, you need to collect yourself and answer calmly who they really are. Say the truth on who they are if you know it will be well. However, if you have been creepy about what you have been doing and you know it will not be well, lie but maintain the composure like it is something normal.
Just make sure that you do not raise any suspicions whatsoever even if you are in direct eye contact. That's for the cheaters.
Besides, your reaction prior to answering that will also have to be decent. For example, if you literally get angry at the question and suggest they have a look at the phone, it will only, in some way, be suggestive that there is more behind the scenes. It will only work against you.
Always remember to keep your composure. Reply confidently and give a brief description of who you have been talking to. That 'description' does not have to be true or real. It is up to you to make sure it sounds very true.
