I’ll try to make this short

So basically I’ve been with my boyfriend for a year and he’s the first man I’ve ever trusted completely he adores me and my daughter.

I’ve been in a 2 abusive relationships where I was physically and mentally abused for years and when you come out of those things (as some of you will unfortunately know) you can notice things a lot easier, for example signs of cheating or drug abuse etc.

Anyway, me and my boyfriend had an argument a couple of nights ago (we have had about 3 arguments in total) I told him I was upset and he basically said that I don’t need to keep telling him I’m unhappy because he already knows and there isn’t anything he can do to fix it right now because of our financial situation and wanting to buy a house etc, we were barely speaking and he came into my work the night after to bring me snacks and to apologise basically.

I noticed on the bag he’d brought in was a ripped up sticker off some flowers, he didn’t get me flowers… I didn’t bring it up because I was too exhausted after working late but I mentioned it to him just now and he said someone must of left it on the self check out and it’s stuck to the bag so I questioned him on it saying nobody has time to rip the sticker off the flowers and rip it up at a self check out. His reply was I wouldn’t buy flowers from tesco they’re sh*te… so I asked him where does he get my flowers from, he said Asda 🙃 he never shops at asda, ever.

He just keeps saying now he hasn’t done anything and he doesn’t know where it’s come from and that he loves me and I’m his world and he’d never cheat on me etc etc

Please help me am I just looking into this wayyyyy too much because I’m scared I’m getting cheated on again or does he sound a bit suspicious?
