Search Results: do i get her a valentine''s day gift

We have been broken up for a year. We had an almost relationship because she had to move. Dont have each others numbers anymore and also i took her off my socials to move on. I bumped into her on Valentines day and was just walking by her and was going to just wave but she insited on chattingg to me, smiling heaps, then i had a gift in my hands and she said 'aww are they for me' and 'what did you get me?' jokingly. Then we had a small chat and i left. (Present was for my niece)

Why was she being like this? Just curious to know what she would be thinking...

Wife goes to a male coworkers house yesterday (day before Valentine's day) to get "a tattoo". Probably did it in his room. He lives with family. she wouldn't change the date of getting the tattoo. said she all ready paid him for it. Says it'll only take 2-3/hours to get about five big stars and a few tiny ones. she texts 4 hours later saying it's gonna take some more time to finish because "the tattoo gun broke & needs to fixed" so in short. she's getting something permanently placed on her shoulder ( i believe getting a tattoo is kinda of an intimate thing considering its permanent.) by a coworker at his house, possibly in his room, on the night before Valentines day; then say you need more time. Does Any of that sound right?
Now behind the scenes: i originally thought she was going to get it done at tatoo parlor. I don't trust the guy. He acts like player from what I hear. My wife talks highly of him all the time. she laughs at all the text or snap chats he sends her. they hangout a lot even though she says they're with her other co-workers. who are are a couple and best friends with the guy. I work nights. with commute I'm gone 12 hours. she leaves the kids with her sister when she goes hangs out when I'm at work. He did art work on a laptop case of hers. she's bought him random gifts throughout the year from the dollar store. i dont even do that for my friends unless it birthday or Christmas. she's never done that before. I'm sure there's other stuff to list but I my gut tells me something isn't right and doesn't sit well with me. I've confronted her about it and she denies cheating on me. she says she doesn't find him attractive when I've heard her say other. she says I'm tripping. I was a paralegal/investigator for family/criminal law. so maybe she's right. but when so many red flags go off & so many coincidences it's hard not to see or connect them. probably got chalk it up to paranoia so the kids don't suffer. but i just wanna here some of your thoughts.
