6th sence ??

okaay soo long story short ... my SO texted his mom asking her if he had one of his cousins number that lived in Colorado sooo right before we went to bed i asked him if he got his number and comunicated with him ... and he said that his mom only had his aunts number and that he texted that number but that number never replaied back so his mom hade asked his younger brother to contact him tru facebook ( we dont have a fb ) and that his cousin replied back and he gave his brother his number ... so my SO brother gives him his cousins number tru a text .. my SO texted that number and that no one replied back so i asked him if his cousin hade whats app and he said yeeah but on the profile picture a women with a little girl come out .. so that number texted back saying that it wasent who they were looking for ... soo know my " 6th sence as a women " have kicked in yes i think my SO is cheating on me ... i have so many other reasons to think this because like on sunday i told him i was going to church with him ( i dont like to go to church ) and he later on said that he wasemt feeling well and he wasent going to .. 2nd hes always talking on the phone latety and he always leaves like if he dosent want me to hear whoa hes talking to , everytime i check his phone is like if he deleats everything ... srry for the long post i just need advice on what to do 😳😳
